[Ant Vespera]
Behold an high priest, * who in his days pleased God, and was found righteous;;109
None was found like unto him, * to keep the Law of the Most High;;110
Therefore the Lord assured him * by an oath that He would multiply his seed among His people;;111
O all ye Priests of God, * bless ye the Lord O all ye servants of the Lord, sing praises unto our God;;112
Good and faithful servant, * enter thou into the joy of thy Lord

[Hymnus Vespera]
v. 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.

[Versum 1]
V. The Lord loved him and beautified him.
R. He clothed him with a robe of glory.

[Ant 1]
Thou art the Shepherd * of the sheep, and the Prince of the Apostles, and unto~
thee are given the keys of the kingdom of heaven.

[Oratio]
v. O God, Who hast given unto thy Blessed Apostle Peter the keys of the kingdom~
of heaven, and the power to bind and to loose, loose us, we beseech thee, at his~
mighty intercession, from all the bands of our sins.

Lesson from the first letter of St Peter the Apostle
!1 Pet 1:1-5
1 Peter, an apostle of Jesus Christ, to the strangers dispersed through Pontus,~
Galatia, Cappadocia, Asia, and Bithynia, elect,
2 According to the foreknowledge of God the Father, unto the sanctification of~
the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace~
unto you and peace be multiplied.
3 Blessed be the God and Father of our Lord Jesus Christ, who according to his~
great mercy hath regenerated us unto a lively hope, by the resurrection of Jesus~
Christ from the dead,
4 Unto an inheritance incorruptible, and undefiled, and that can not fade,~
reserved in heaven for you,
5 Who, by the power of God, are kept by faith unto salvation, ready to be~
revealed in the last time.

[Responsory1]
R. Simon Peter, before I called thee out of the ship, I knew thee, and appointed~
thee for a ruler over My people.
* And I have given unto thee the keys of the kingdom of heaven.
V. Whatsoever, thou shalt bind on earth, shall be bound in heaven; and~
whatsoever thou shalt loose on earth, shall be loosed in heaven.
R. And I have given unto thee the keys of the kingdom of heaven.

[Lectio2]
!1 Pet 1:6-9
6 Wherein you shall greatly rejoice, if now you must be for a little time made~
sorrowful in divers temptations:
7 That the trial of your faith much more precious than gold which is tried by~
the fire) may be found unto praise and glory and honour at the appearing of~
Jesus Christ:
8 Whom having not seen, you love: in whom also now, though you see him not, you~
believe: and believing shall rejoice with joy unspeakable and glorified;
9 Receiving the end of your faith, even the salvation of your souls.

[Responsory2]
R. Simon Peter, if thou lovest Me, feed My sheep. Lord, Thou knowest that I love~
thee
* I will lay down my life for thy sake.
V. If I should die with thee, I will not deny thee.
R. I will lay down my life for thy sake.

[Lectio3]
!1 Pet 1:10-12
10 Of which salvation the prophets have inquired and diligently searched, who~
prophesied of the grace to come in you.
11 Searching what or what manner of time the Spirit of Christ in them did~
signify: when it foretold those sufferings that are in Christ, and the glories~
that should follow:
12 To whom it was revealed, that not to themselves, but to you they ministered~
those things which are now declared to you by them that have preached the gospel~
to you, the Holy Ghost being sent down from heaven, on whom the angels desire to~
look.

[Responsory3]
R. Thou art Peter, and upon this rock I will build My Church, and the gates of~
hell shall not prevail against it.
* And I will give unto thee the keys of the kingdom of heaven.
V. Whatsoever thou shalt bind on earth, shall be bound in heaven; and whatsoever~
thou shalt loose on earth, shall be loosed in heaven.
R. And I will give unto thee the keys of the kingdom of heaven.
&Gloria
R. And I will give unto thee the keys of the kingdom of heaven.

From the Sermons of St Austin, Bishop (of Hippo.) 
!16th on the Saints. 
The solemn Feast of to-day received from our forefathers the name of that of St~
Peter's Chair at Antioch, because there is a tradition that it was on this day~
that Peter, first of the Apostles, was enthroned in a Bishop's Chair. Rightly,~
therefore, do the Churches observe the first day of that Chair, the right to~
which the Apostle received for the salvation of the Churches from the Lord of~
the Churches Himself, with the words Thou art Peter, and upon this rock I will~
build My Church.

[Responsory4]
R. Thou art the Shepherd of the sheep, and the Prince of the Apostles, and unto~
thee hath God given all the kingdoms of the world.
* Therefore unto thee hath He given the keys of the kingdom of heaven.
V. Whatsoever thou shalt bind on earth shall be bound in heaven; and whatsoever~
thou shalt loose on earth shall be loosed in heaven.
R. Therefore unto thee hath He given the keys of the kingdom of heaven.

[Lectio5]
It was the Lord Himself Who called Peter the foundation of the Church, and~
therefore it is right that the Church should reverence this foundation whereon~
her mighty structure riseth. Justly is it written in the Psalm which we have~
just heard Let them exalt him in the congregation of the people, and praise~
him in the assembly of the elders. Blessed be God, Who hath commanded that the~
Blessed Apostle Peter should be exalted in the congregation! Worthy to be~
honoured by the Church is that foundation from which her goodly towers rise,~
pointing to heaven!

[Responsory5]
R. Peter, I have prayed for thee, that thy faith fail not
* And when thou art converted, strengthen thy brethren.
V. Flesh and blood hath not revealed it unto thee, but My Father Which is in~
heaven.
R. And when thou art converted, strengthen thy brethren.

[Lectio6]
In the honour which is this day paid to the inauguration of the first Bishop's~
throne, an honour is paid to the office of all Bishops. The Churches testify one~
to another, that, the greater the Church's dignity, the greater the reverence~
due to her priests. While I confess how rightly godly custom hath exalted this~
Feast in the estimation of all the Churches, the more do I wonder at the growth~
of that unhealthy error which at this day causeth some unbelievers to lay food~
and wine upon the graves of the dead, as if souls once rid of the body had any~
longer any need of bodily refreshment.

[Responsory6]
R. Peter, lovest thou Me? Lord, Thou knowest that I love thee.
* Feed My sheep.
V. Simon, son of Jonas, lovest thou Me more than these? Lord, Thou knowest that I~
love thee.
R. Feed My sheep.
&Gloria
R. Feed My sheep.

From the Holy Gospel according to Matthew
!Matt 16:13-19
At that time Jesus came into the coasts of Caesarea Philippi, and He asked His~
disciples, saying Who do men say that I, the Son of Man am? And so on.
_
Homily by Pope St Leo (the Great.)
!3rd on the Anniversary of his own election.
The Lord asked His disciples Who men said that He was, and their answers were~
human as long as they were the answers of human reason, unilluminated by Divine~
light. At last, when the glimmerings of earthly conjecture were spoken, he whose~
Apostleship is the first in dignity, was the first to confess his Lord. And~
Simon Peter answered and said: Thou art the Christ, the Son of the living God.~
And Jesus answered and said unto him Blessed art thou, Simon Barjona, for~
flesh and blood hath not revealed it unto thee, but My Father Which is in~
heaven. That is to say, For this cause art thou blessed, because My Father~
Himself hath taught thee; the opinions of men have not beguiled thee, the voices~
of angels have not taught thee, not flesh and blood, but He, Whose Only begotten~
Son I am, hath revealed Me unto thee.

[Responsory7]
R. Jesus asked His disciples, saying Who do men say that I, the Son of Man,~
am? Peter answered, and said Thou art the Christ, the Son of the living God.
* And I say unto thee, that thou art Peter, and upon this rock I will build My~
Church.
V. Blessed art thou, Simon Barjona, for flesh and blood hath not revealed it~
unto thee, but My Father Which is in heaven.
R. And I say unto thee, that thou art Peter, and upon this rock I will build My~
Church.

[Lectio8]
Thus saith the Lord unto Simon Peter: And I say also unto thee, That thou art~
Peter. That is to say, Even as My Father hath revealed unto thee concerning Me~
that I am God, even so now will I also reveal unto thee that thou art Peter; I~
am the sure Rock of defence, the Corner Stone, Who make both one, (Eph. ii. 20,~
15,) I am the Foundation, beside Which other can no man lay, (1 Cor. iii. 11,)~
and thou also art a rock, in My Strength made hard, and those things whereof I~
by right am Lord, into thy hand do I give them, that thou mayst bear rule over~
them, for Me, and with Me. And upon this rock I will build My Church, and the~
gates of hell shall not prevail against it. Upon this strength of thine, whereof I~
am the Strength, I will build My eternal temple, and upon the truth of thy~
confession of Me I will make to rise that My glorious Church whose spires shall~
pierce to heaven.

[Responsory8]
R. The Lord hath chosen thee for a priest unto Himself, to offer up unto Him
* The sacrifice of praise.
V. Offer unto God thanksgiving, and pay thy vows unto the Most High.
R. The sacrifice of praise.
&Gloria
R. The sacrifice of praise.

[Lectio9]
Against this confession the gates of hell shall never prevail, neither shall the~
bands of death take hold upon it. Thus saith He That is faithful and true. And~
as this confession hath power to lift up to heaven them that make it, so is it~
able to thrust down to hell them that gainsay it. Wherefore it is said unto the~
most blessed Peter And I will give unto thee the keys of the kingdom of heaven~
and whatsoever thou shalt bind on earth, shall be bound in heaven; and~
whatsoever thou shalt loose on earth, shall be loosed in heaven. This power~
passed indeed to the other Apostles also; this the Lord's will had effect in~
them; but it is not in vain that it is written that that was given to one which~
passed from him to all. To Peter alone were the keys given, and Peter is set as~
the pattern for all them that bear rule in the Church to follow. There remaineth~
therefore the right of Peter, wheresoever his judgment decreeth justice. Neither~
is there anything too hard, or too lax, where there is nothing bound and nothing~
loosed, save when Peter bindeth or looseth.
&teDeum

[Hymnus Laudes]
v. Peter, blest shepherd, hearken to our cry,
And with a word unloose our guilty chain;
Thou! who hast power to open the gates on high
To men below, and power to shut them fast again.
_
Praise, blessing, majesty, through endless days,
Be to the Trinity immortal given;
Who in pure unity profoundly sways
Eternally alike all things in earth and heaven.
Amen.

[Versum 2]
V. Let them exalt Him in the congregation of the people.
R. And praise Him in the assembly of the elders.

[Ant 2]
Thus saith the Lord * unto Simon Peter Whatsoever thou shalt bind on earth,~
shall be bound in heaven; and whatsoever thou shalt loose on earth, shall be~
loosed in heaven.

[Versum 3]
V.  The Lord chose him as a priest unto himself.
R.  To offer unto him the Sacrifice of Thanksgiving.

[Ant 3]
While he was supreme Pontiff, * he feared not earthly powers, but gloriously went his way to the heavenly kingdom.
