Invitatorium

Ant. Tu es pastor óvium, Princeps Apostolórum: * Tibi trádidit Deus claves regni cælórum.

Veníte, exsultémus Dómino, jubilémus Deo, salutári nostro: præoccupémus fáciem ejus in confessióne, et in psalmis jubilémus ei.

Ant. Tu es pastor óvium, Princeps Apostolórum: * Tibi trádidit Deus claves regni cælórum.

Quóniam Deus magnus Dóminus, et Rex magnus super omnes deos, quóniam non repéllet Dóminus plebem suam: quia in manu ejus sunt omnes fines terræ, et altitúdines móntium ipse cónspicit.

Ant. Tibi trádidit Deus claves regni cælórum.

Quóniam ipsíus est mare, et ipse fecit illud, et áridam fundavérunt manus ejus (genuflectitur) veníte, adorémus, et procidámus ante Deum: plorémus coram Dómino, qui fecit nos, quia ipse est Dóminus, Deus noster; nos autem pópulus ejus, et oves páscuæ ejus.

Ant. Tu es pastor óvium, Princeps Apostolórum: * Tibi trádidit Deus claves regni cælórum.

Hódie, si vocem ejus audiéritis, nolíte obduráre corda vestra, sicut in exacerbatióne secúndum diem tentatiónis in desérto: ubi tentavérunt me patres vestri, probavérunt et vidérunt ópera mea.

Ant. Tibi trádidit Deus claves regni cælórum.

Quadragínta annis próximus fui generatióni huic, et dixi: Semper hi errant corde, ipsi vero non cognovérunt vias meas: quibus jurávi in ira mea: Si introíbunt in réquiem meam.

Ant. You are the shepherd of the sheep, the Prince of the Apostles: * To you God has entrusted the keys of the Kingdom of Heaven.

Come, let us exult in the Lord. Let us shout joyfully to God, our Savior. Let us anticipate his presence with confession, and let us sing joyfully to him with psalms.

Ant. You are the shepherd of the sheep, the Prince of the Apostles: * To you God has entrusted the keys of the Kingdom of Heaven.

For the Lord is a great God and a great King over all gods. For the Lord will not drive away his people. For in his hand are all the limits of the earth, and he beholds the heights of the mountains.

Ant. To you God has entrusted the keys of the Kingdom of Heaven.

For the sea is his, and he made it, and his hands established the dry land. (kneel) Come, let us adore and fall prostrate before God, and let us weep before the Lord who made us. For he is the Lord our God, and we are his people and the sheep of his pasture.

Ant. You are the shepherd of the sheep, the Prince of the Apostles: * To you God has entrusted the keys of the Kingdom of Heaven.

If today you hear his voice, harden not your hearts: as in the provocation, according to the day of temptation in the wilderness, where your fathers tempted me; they tested and saw my works.

Ant. To you God has entrusted the keys of the Kingdom of Heaven.

For forty years, I was near to that generation, and I said: These have always strayed in heart. But they have not known my ways. To them I swore in my wrath: They shall not enter into my rest.

Ant. You are the shepherd of the sheep, the Prince of the Apostles: * To you God has entrusted the keys of the Kingdom of Heaven.

℣ Glory be to the Father, and to the Son, * and to the Holy Spirit.

℟ As it was in the beginning, is now, and ever shall be, * world without end. Amen.

Hymnus

Quodcúmque in orbe néxibus revínxeris,

Erit revínctum, Petre, in arce síderum:

Et quod resólvit hic potéstas trádita,

Erit solútum cæli in alto vértice;

In fine mundi judicábis sǽculum.

Patri perénne sit per ævum glória,

Tibíque laudes concinámus ínclitas,

Ætérne Nate; sit, supérne Spíritus,

Honor tibi decúsque: sancta júgiter

Laudétur omne Trínitas per sǽculum.

Amen.

Peter, whatever thou shalt bind on earth,

The same is bound above the starry sky;

What here thy delegated power doth loose,

Is loosed in heaven's supremest court on high:

To judgement shalt thou come, when the world's end is nigh.

Praise to the Father, through all ages be;

Praise to the consubstantial sovereign Son,

And Holy Ghost, one glorious Trinity;

To whom all majesty and might belong;

So sing we now, and such be our eternal song.

Amen.

Sermo sancti Augustíni Epíscopi

Sermo 15 de Sanctis

Institútio solemnitátis hodiérnæ a senióribus nostris Cáthedræ nomen accépit, ídeo quod primus Apostolórum Petrus hódie episcopátus cáthedram suscepísse referátur. Recte ergo ecclésiæ natálem sedis illíus colunt, quam Apóstolus pro ecclesiárum salúte suscépit, dicénte Dómino: Tu es Petrus, et super hanc petram ædificábo Ecclésiam meam.

℣ Tu autem, Dómine, miserére nobis.

℟ Deo grátias.

℟ Tu es pastor óvium, princeps Apostolórum: tibi trádidit Deus ómnia regna mundi:

* Et ídeo tibi tráditæ sunt claves regni cælórum.

℣ Quodcúmque ligáveris super terram, erit ligátum et in cælis; et quodcúmque sólveris super terram, erit solútum et in cælis.

℟ Et ídeo tibi tráditæ sunt claves regni cælórum.

℣ Jube, Dómine, benedícere.

Benedictio. Christus perpétuæ det nobis gáudia vitæ.

℟ Amen.

Lectio 5

Petrum ítaque fundaméntum Ecclésiæ Dóminus nominávit: et ídeo digne fundaméntum hoc Ecclésia colit, supra quod ecclesiástici ædifícii altitúdo consúrgit. Unde conveniénter psalmus, qui lectus est, dicit: Exáltent eum in ecclésia plebis, et in cáthedra seniórum laudent eum. Benedíctus Deus, qui beátum Petrum Apóstolum in Ecclésia exaltári præcépit: quia dignum est ut fundaméntum hoc in Ecclésia honorétur, per quod ad cælum conscénditur.

℣ Tu autem, Dómine, miserére nobis.

℟ Deo grátias.

℟ Ego pro te rogávi, Petre, ut non defíciat fides tua:

* Et tu aliquándo convérsus confírma fratres tuos.

℣ Caro et sanguis non revelávit tibi, sed Pater meus, qui est in cælis.

℟ Et tu aliquándo convérsus confírma fratres tuos.

℣ Jube, Dómine, benedícere.

Benedictio. Ignem sui amóris accéndat Deus in córdibus nostris.

℟ Amen.

Lectio 6

Quod natális ergo Cáthedræ hódie cólitur, sacerdotále honorátur offícium. Sibi hoc Ecclésiæ ínvicem præstant, quia tanto necésse plus habet Ecclésia dignitatis, quanto sacerdotále offícium plus honóris. Cum solemnitátem hanc Ecclésiis mérito religiósa observátio introdúxerit, miror, cur apud quosdam infidéles hódie tam perniciósus error incréverit, ut super túmulos defunctórum cibos et vina conférant, quasi egréssæ de corpóribus ánimæ carnáles cibos requírant.

℣ Tu autem, Dómine, miserére nobis.

℟ Deo grátias.

℟ Petre, amas me? Tu scis, Dómine, quia amo te.

* Pasce oves meas.

℣ Simon Joánnis, díligis me plus his? Tu scis, Dómine, quia amo te.

℟ Pasce oves meas.

℣ Glória Patri, et Fílio, * et Spirítui Sancto.

℟ Pasce oves meas.

14:3a Qui lóquitur veritátem in corde suo, * qui non egit dolum in lingua sua:

14:3b Nec fecit próximo suo malum, * et oppróbrium non accépit advérsus próximos suos.

14:4a Ad níhilum dedúctus est in conspéctu ejus malígnus: * timéntes autem Dóminum gloríficat:

14:4b Qui jurat próximo suo, et non décipit, * (5a) qui pecúniam suam non dedit ad usúram, et múnera super innocéntem non accépit.

Psalmus 20 [8]

20:2 Dómine, in virtúte tua lætábitur rex: * et super salutáre tuum exsultábit veheménter.

20:3 Desidérium cordis ejus tribuísti ei: * et voluntáte labiórum ejus non fraudásti eum.

20:6 Magna est glória ejus in salutári tuo: * glóriam et magnum decórem impónes super eum.

20:7 Quóniam dabis eum in benedictiónem in sǽculum sǽculi: * lætificábis eum in gáudio cum vultu tuo.

20:8 Quóniam rex sperat in Dómino: * et in misericórdia Altíssimi non commovébitur.

20:9 Inveniátur manus tua ómnibus inimícis tuis: * déxtera tua invéniat omnes, qui te odérunt.

20:10 Pones eos ut clíbanum ignis in témpore vultus tui: * Dóminus in ira sua conturbábit eos, et devorábit eos ignis.

20:11 Fructum eórum de terra perdes: * et semen eórum a fíliis hóminum.

20:12 Quóniam declinavérunt in te mala: * cogitavérunt consília, quæ non potuérunt stabilíre.

20:13 Quóniam pones eos dorsum: * in relíquiis tuis præparábis vultum eórum.

20:14 Exaltáre, Dómine, in virtúte tua: * cantábimus et psallémus virtútes tuas.

℣ Glória Patri, et Fílio, * et Spirítui Sancto.

℟ Sicut erat in princípio, et nunc, et semper, * et in sǽcula sæculórum. Amen.

23:3 Quis ascéndet in montem Dómini? * aut quis stabit in loco sancto ejus?

Léctio sancti Evangélii secúndum Matthǽum

Matt 16:13-19

In illo témpore: Venit Jesus in partes Cæsaréæ Philíppi, et interrogábat discípulos suos, dicens: Quem dicunt hómines esse Fílium hóminis? Et réliqua.

Homilía sancti Leónis Papæ

Sermo 3 in annivers. assumpt. suæ, post initium

Apóstolos Dóminus, quid de se hómines opinéntur, intérrogat: et tamdiu sermo respondéntium commúnis est, quámdiu humánæ intellegéntiæ ambigúitas explicátur. At ubi quid hábeat sensus discipulórum exígitur, primus est in Dómini confessióne, qui primus est in apostólica dignitáte. Qui cum dixísset: Tu es Christus Fílius Dei vivi: respóndit ei Jesus: Beátus es Simon Bar-Jona, quia caro et sanguis non revelávit tibi, sed Pater meus, qui in cælis est. Id est, Ideo beátus es, quia Pater meus te dócuit: nec terréna opínio te feféllit, sed inspirátio cæléstis instrúxit: et non caro et sanguis, sed ille me tibi, cujus sum unigénitus Fílius, indicávit.

℣ Tu autem, Dómine, miserére nobis.

℟ Deo grátias.

℟ Quem dicunt hómines esse Filium hóminis? dixit Jesus discípulis suis. Respóndens Petrus dixit: Tu es Christus Fílius Dei vivi.

* Et ego dico tibi, quia tu es Petrus, et super hanc petram ædificábo Ecclésiam meam.

℣ Beátus es, Simon Bar-Jona, quia caro et sanguis non revelávit tibi, sed Pater meus qui est in cælis.

℟ Et ego dico tibi, quia tu es Petrus, et super hanc petram ædificábo Ecclésiam meam.

℣ Jube, Dómine, benedícere.

Benedictio. Cujus festum cólimus, ipse intercédat pro nobis ad Dóminum.

℟ Amen.

Lectio 8

Et ego, inquit, dico tibi: hoc est, sicut Pater meus tibi manifestávit divinitátem meam, ita et ego tibi notam fácio excelléntiam tuam, quia tu es Petrus: id est, cum ego sim inviolábilis petra, ego lapis anguláris, qui fácio útraque unum, ego fundaméntum præter quod nemo potest áliud pónere: tamen tu quoque petra es, quia mea virtúte solidáris, ut quæ mihi potestáte sunt própria, sint tibi mecum participatióne commúnia. Et super hanc petram ædificábo Ecclésiam meam, et portæ ínferi non prævalébunt advérsus eam. Super hanc, inquit, fortitúdinem ætérnum éxstruam templum: et Ecclésiæ meæ cælo inserénda sublímitas, in hujus fídei firmitáte consúrget.

℣ Tu autem, Dómine, miserére nobis.

℟ Deo grátias.

℟ Elégit te Dóminus sacerdótem sibi, ad sacrificándum ei

* Hóstiam laudis.

℣ Immola Deo sacrifícium laudis, et redde Altíssimo vota tua.

℟ Hóstiam laudis.

℣ Glória Patri, et Fílio, * et Spirítui Sancto.

℟ Hóstiam laudis.

℣ Jube, Dómine, benedícere.

Benedictio. Ad societátem cívium supernórum perdúcat nos Rex Angelórum.

℟ Amen.

Lectio 9

Hanc confessiónem portæ ínferi non tenébunt, mortis víncula non ligábunt: vox enim ista vox vitæ est. Et sicut confessóres suos in cæléstia próvehit, ita negatóres ad inférna demérgit. Propter quod dicit beatíssimo Petro: Tibi dabo claves regni cælórum: Et quæcúmque ligáveris super terram, erunt ligáta et in cælis: et quæcúmque sólveris super terram, erunt solúta et in cælis. Transívit quidem étiam in álios Apóstolos vis potestátis istíus, et ad omnes Ecclésiæ príncipes decréti hujus constitútio commeávit: sed non frustra uni commendátur, quod ómnibus intimátur. Petro enim ídeo hoc singuláriter créditur, quia cunctis Ecclésiæ rectóribus Petri forma præpónitur. Manet ergo Petri privilégium, ubicúmque ex ipsíus fertur æquitáte judícium. Nec nímia est vel sevéritas vel remíssio, ubi nihil erit ligátum, nihil solútum, nisi quod beátus Petrus aut sólverit, aut ligáverit.

℣ Tu autem, Dómine, miserére nobis.

℟ Deo grátias.

Psalm 2 [2]

2:1 Why have the Gentiles been seething, * and why have the people been pondering nonsense?

2:2 The kings of the earth have stood up, and the leaders have joined together as one, * against the Lord and against his Christ:

2:3 “Let us shatter their chains * and cast their yoke away from us.”

2:4 He who dwells in heaven will ridicule them, * and the Lord will mock them.

2:5 Then will he speak to them in his anger * and trouble them with his fury.

2:6 Yet I have been appointed king by him over Zion, his holy mountain, * preaching his precepts.

2:7 The Lord has said to me: * You are my son, this day have I begotten you.

2:8 Ask of me and I will give to you: the Gentiles for your inheritance, * and the ends of the earth for your possession.

2:9 You will rule them with an iron rod, * and you will shatter them like a potter’s vessel.

2:10 And now, O kings, understand. * Receive instruction, you who judge the earth.

2:11 Serve the Lord in fear, * and exult in him with trembling.

Lesson 1

Here begins the first Epistle of the blessed Apostle Peter

1 Pet 1:1-5

1 Peter, Apostle of Jesus Christ, to the newly-arrived elect of the dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,

2 In accord with the foreknowledge of God the Father, in the sanctification of the Spirit, with the obedience and the sprinkling of the blood of Jesus Christ: May grace and peace be multiplied for you.

3 Blessed be the God and Father of our Lord Jesus Christ, who according to his great mercy has regenerated us into a living hope, through the resurrection of Jesus Christ from the dead:

4 Unto an incorruptible and undefiled and unfading inheritance, which is reserved for you in heaven.

5 By the power of God, you are guarded through faith for a salvation which is ready to be revealed in the end time.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ Simon Peter, before I called you from the boat, I knew you and appointed you as prince over my people:

* And I gave you the keys of the kingdom of heaven.

Lesson 2

1 Pet 1:6-9

6 In this, you should exult, if now, for a brief time, it is necessary to be made sorrowful by various trials,

7 So that the testing of your faith, which is much more precious than gold tested by fire, may be found in praise and glory and honor at the revelation of Jesus Christ.

8 For though you have not seen him, you love him. In him also, though you do not see him, you now believe. And in believing, you shall exult with an inexpressible and glorious joy,

9 Returning with the goal of your faith, the salvation of souls.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ Simon Peter, if you love me, feed my sheep. Lord, you know that I love you,

* And I lay down my soul for you.

Lesson 3

1 Pet 1:10-12

10 About this salvation, the prophets inquired and diligently searched, those who prophesied about the future grace in you,

11 Inquiring as to what type of condition was signified to them by the Spirit of Christ, when foretelling those sufferings that are in Christ, as well as the subsequent glories.

12 To them, it was revealed that they were ministering, not for themselves, but for you those things which have now been announced to you through those who have preached the Gospel to you, through the Holy Spirit, who was sent down from heaven to the One upon whom the Angels desire to gaze.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ You are Peter, and upon this rock I will build my Church, and the gates of Hell shall not prevail against it:

* And I will give you the keys of the kingdom of heaven.

℟ And I will give you the keys of the kingdom of heaven.

℣ Glory be to the Father, and to the Son, * and to the Holy Spirit.

Nocturn II

Ant. The Lord heeded * his holy one when he called; the Lord heeded him, and established him in peace.

Psalm 4 [4]

4:2a When I called upon him, the God of my justice heeded me. * In tribulation, you have enlarged me.

4:2b Have mercy on me, * and heed my prayer.

4:3 Sons of men, how long will you be dull in heart, * so that whatever you love is in vain, and whatever you seek is false?

4:4 And know this: the Lord has made wondrous his holy one. * The Lord will heed me when I cry out to him.

4:5 Be angry, and do not be willing to sin. † The things that you say in your hearts: * be sorry for them on your beds.

5:7b The bloody and deceitful man, the Lord will abominate. * (8a) But I am in the multitude of your mercy.

5:8b I will enter your house. * I will show adoration toward your holy temple, in your fear.

8:2b For your magnificence is elevated * above the heavens.

8:3 Out of the mouths of babes and infants, you have perfected praise, because of your enemies, * so that you may destroy the enemy and the revenger.

8:4 For I will behold your heavens, the works of your fingers: * the moon and the stars, which you have founded.

8:5 What is man, that you are mindful of him, * or the son of man, that you visit him?

8:6 You reduced him to a little less than the Angels; † you have crowned him with glory and honor, * (7) and you have set him over the works of your hands.

8:8 You have subjected all things under his feet, * all sheep and oxen, and in addition: the beasts of the field,

8:9 the birds of the air, and the fish of the sea, * which pass through the paths of the sea.

Lesson 4

Sermon of Saint Augustine, Bishop

Sermon 15 on the Saints

The institution of today's solemnity received from our elders the name "Chair," because the first of the Apostles, Peter, is reported to have taken up the chair of the episcopate on this day. Rightly, therefore, do the churches celebrate the birthday of that seat which the Apostle received for the salvation of the churches, as the Lord said: You are Peter, and upon this rock I will build my Church.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ You are the shepherd of the sheep, the prince of the Apostles: to you God has entrusted all the kingdoms of the world:

* And therefore to you are given the keys of the kingdom of heaven.

℣ Whatever you shall bind on earth shall be bound, even in heaven; and whatever you shall release on earth shall be released, even in heaven.

℟ And therefore to you are given the keys of the kingdom of heaven.

℣ Grant a blessing, O Lord.

Benediction. May Christ grant us the joys of eternal life.

℟ Amen.

Lesson 5

The Lord therefore named Peter the foundation of the Church: and for that reason the Church fittingly venerates this foundation upon which the height of the ecclesiastical edifice rises. Hence the psalm that was read aptly says: Let them exalt him in the assembly of the people, and let them praise him in the seat of the elders. Blessed is God, who commanded the blessed Apostle Peter to be exalted in the Church: for it is fitting that this foundation be honored in the Church, through which the ascent to heaven is made.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ I have prayed for you, Peter, that your faith may not fail:

* and you, when once you have turned back, confirm your brothers.

℣ Flesh and blood has not revealed this to you, but my Father, who is in heaven.

℟ and you, when once you have turned back, confirm your brothers.

℣ Grant a blessing, O Lord.

Benediction. May God kindle the fire of his love in our hearts.

℟ Amen.

Lesson 6

That the birthday of the Chair is therefore celebrated today, the priestly office is honored. The churches confer this upon one another, for the Church necessarily has as much greater dignity as the priestly office has greater honor. Since religious observance has rightly introduced this solemnity to the Churches, I wonder why among certain unbelievers today so pernicious an error has grown, that they place food and wine upon the tombs of the dead, as though souls that have departed from their bodies were in need of bodily food.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ Peter, do you love me? You know, Lord, that I love you.

* Feed my sheep.

℣ Simon, son of John, do you love me more than these? You know, Lord, that I love you.

℟ Feed my sheep.

℣ Glory be to the Father, and to the Son, * and to the Holy Spirit.

℟ Feed my sheep.

Nocturn III

Ant. O Lord, * this Saint will dwell in your tabernacle; he has worked justice and will rest on your holy mountain.

Psalm 14 [7]

14:2 He who walks without blemish * and who works justice.

14:3a He who speaks the truth in his heart, * who has not acted deceitfully with his tongue,

14:3b and has not done evil to his neighbor, * and has not taken up a reproach against his neighbors.

14:4a In his sight, the malicious one has been reduced to nothing, * but he glorifies those who fear the Lord.

14:4b He who swears to his neighbor and does not deceive. * (5a) He who has not given his money in usury, nor accepted bribes against the innocent.

14:5b He who does these things * will be undisturbed for eternity.

℣ Glory be to the Father, and to the Son, * and to the Holy Spirit.

℟ As it was in the beginning, is now, and ever shall be, * world without end. Amen.

Ant. O Lord, this Saint will dwell in your tabernacle; he has worked justice and will rest on your holy mountain.

Psalm 20 [8]

20:2 In your virtue, Lord, the king will rejoice, * and over your salvation, he will exult exceedingly.

20:3 You have granted him the desire of his heart, * and you have not cheated him of the wish of his lips.

20:4 For you have gone ahead of him with blessings of sweetness. * You have placed a crown of precious stones on his head.

20:5 He petitioned you for life, * and you have granted him length of days, in the present time, and forever and ever.

20:6 Great is his glory in your salvation. * Glory and great adornment, you will lay upon him.

20:7 For you will give him as a blessing forever and ever. * You will make him rejoice with gladness in your presence.

20:8 Because the king hopes in the Lord, * and in the mercy of the Most High, he will not be disturbed.

20:9 May your hand be found by all your enemies. * May your right hand discover all those who hate you.

20:10 You will make them like an oven of fire, in the time of your presence. * The Lord will stir them up with his wrath, and fire will devour them.

20:11 You will destroy their fruit from the earth * and their offspring from the sons of men.

20:12 For they have turned evils upon you; * they have devised plans, which they have not been able to accomplish.

20:13 For you will make them turn their back; * with your remnants, you will prepare their countenance.

20:14 Be exalted, Lord, by your own power. * We will play music and sing psalms to your virtues.

℣ Glory be to the Father, and to the Son, * and to the Holy Spirit.

℟ As it was in the beginning, is now, and ever shall be, * world without end. Amen.

Ant. He petitioned you for life, and you have granted it to him, O Lord; glory and great adornment you have laid upon him; you have placed a crown of precious stones on his head.

Ant. He will receive * a blessing from the Lord, and mercy from God, his Savior: for this is the generation that seeks the Lord.

Psalm 23 [9]

23:1 The earth and all its fullness belong to the Lord: * the whole world and all that dwells in it.

23:2 For he has founded it upon the seas, * and he has prepared it upon the rivers.

23:3 Who will ascend to the mountain of the Lord? * And who will stand in his holy place?

23:4 The innocent of hands and the clean of heart, * who has not received his soul in vain, nor sworn deceitfully to his neighbor.

23:5 He will receive a blessing from the Lord, * and mercy from God, his Savior.

Lesson 7

A Reading from the holy Gospel according to Matthew

Matthew 16:13-19

At that time: Jesus went into parts of Caesarea Philippi. And he questioned his disciples, saying, “Who do men say that the Son of man is?” And so forth.

A Homily of Saint Leo the Pope

Sermon 3 on the anniversary of his accession, after the beginning

The Lord asks the Apostles what men think of him; and the discourse of those who answer remains general for as long as the ambiguity of human understanding is being unraveled. But when an account is required of what the disciples themselves think, he who is first in apostolic dignity is first in the confession of the Lord. And when he had said: You are the Christ, the Son of the living God, Jesus answered him: Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven. That is to say: You are blessed for this reason — because my Father has taught you; earthly opinion has not deceived you, but heavenly inspiration has instructed you; and not flesh and blood, but he whose only-begotten Son I am, has made me known to you.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ Jesus said to his disciples, 'Who do men say that the Son of Man is?' Peter answered and said, 'You are the Christ, the Son of the living God.'

* And I say to you, that you are Peter, and upon this rock I will build my Church.

℣ Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my Father, who is in heaven.

℟ And I say to you, that you are Peter, and upon this rock I will build my Church.

℣ Grant a blessing, O Lord.

Benediction. May he whose feast we celebrate intercede for us to the Lord.

℟ Amen.

Lesson 8

And I, he says, say to you: that is, as my Father has manifested to you my divinity, so I also make known to you your excellence, because you are Peter — that is, though I am the inviolable rock, I the cornerstone, who make both one, I the foundation besides which no other can be laid: yet you also are a rock, because you are made firm by my strength, so that those things which are proper to me by power may be shared with me by participation with you. And upon this rock I will build my Church, and the gates of hell shall not prevail against it. Upon this strength, he says, I will raise an eternal temple: and the loftiness of my Church, which is to be set in heaven, will rise on the firmness of this faith.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.

℟ The Lord chose you as priest for himself, to offer him

* A sacrifice of praise.

℣ Offer to God the sacrifice of praise, and pay your vows to the Most High.

℟ A sacrifice of praise.

℣ Glory be to the Father, and to the Son, * and to the Holy Spirit.

℟ A sacrifice of praise.

℣ Grant a blessing, O Lord.

Benediction. May the King of Angels lead us to the company of the citizens on high.

℟ Amen.

Lesson 9

The gates of hell shall not hold fast this confession, the bonds of death shall not bind it; for that voice is the voice of life. And just as it raises those who confess to the heavenly realms, so it plunges those who deny into the depths below. For this reason he says to the most blessed Peter: To you I will give the keys of the kingdom of heaven; and whatever you bind on earth shall be bound also in heaven, and whatever you loose on earth shall be loosed also in heaven. Indeed, the power of this authority passed also to the other Apostles, and the establishment of this decree spread to all rulers of the Church; but it is not without reason that it is entrusted to one man, even as it is made known to all. For it is entrusted to Peter individually because the form of Peter is set before all who govern the Church. Peter's privilege therefore endures wherever judgment is rendered according to his equity. Nor is there excess in either severity or leniency, where nothing shall be bound, nothing loosed, except what blessed Peter shall either loose or bind.

℣ But you, O Lord, have mercy on us.

℟ Thanks be to God.
