First Lesson: Ezekiel 34:11 – 16
For thus saith the Lord God; Behold, I, even I, will both search my sheep, and seek them out.
As a shepherd seeketh out his flock in the day that he is among his sheep that are scattered; so will I seek out my sheep, and will deliver them out of all places where they have been scattered in the cloudy and dark day.
And I will bring them out from the people, and gather them from the countries, and will bring them to their own land, and feed them upon the mountains of Israel by the rivers, and in all the inhabited places of the country.
I will feed them in a good pasture, and upon the high mountains of Israel shall their fold be: there shall they lie in a good fold, and in a fat pasture shall they feed upon the mountains of Israel.
I will feed my flock, and I will cause them to lie down, saith the Lord God.
I will seek that which was lost, and bring again that which was driven away, and will bind up that which was broken, and will strengthen that which was sick: but I will destroy the fat and the strong; I will feed them with judgment.
Canticle: Magnificat. St. Luke 1:46-55
My soul doth magnify the Lord, * and my spirit hath rejoiced in God my Saviour.
For he hath regarded * the lowliness of his handmaiden.
For behold, from henceforth * all generations shall call me blessed.
For he that is mighty hath magnified me; * and holy is his Name.
And his mercy is on them that fear him * throughout all generations.
He hath showed strength with his arm; * he hath scattered the proud in the imagination of their hearts.
He hath put down the mighty from their seat, * and hath exalted the humble and meek;.
He hath filled the hungry with good things; * and the rich he hath sent empty away.
He remembering his mercy hath holpen his servant Israel; * as he promised to our forefathers, Abraham and his seed, for ever.
Second Lesson: John 21:15 – 22
So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.
He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
Verily, verily, I say unto thee, When thou wast young, thou girdest thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.
This spake he, signifying by what death he should glorify God. And when he had spoken this, he saith unto him, Follow me.
Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee?
Peter seeing him saith to Jesus, Lord, and what shall this man do?
Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me.
Canticle: Nunc dimittis. St. Luke 2:29-32
LORD, now lettest thou thy servant depart in peace, * according to thy word.
For mine eyes have seen * thy salvation,
Which thou hast prepared * before the face of all people;
To be a light to lighten the Gentiles, * and to be the glory of thy people Israel.
A Homily by St. Leo the Pope:
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 the 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 Bar-Jona, 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.
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, I am the Foundation, besides which other can no man lay, 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 mayest 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 mine 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.
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 judgement decreeth justice. Neither is there anything too hard, or too lax, where is nothing bound and nothing loosed, save when Peter bindeth or looseth.
From the Broman Breviary for the day.
And the Apostles Creed and the rest of the office.
O God, who didst bestow upon thy blessed Apostle Peter the keys of the kingdom of heaven, and didst appoint unto him the priesthood for the binding and loosing of sin : grant, we beseech thee ; that by the help of his intercession we may be delivered from the bonds of all our iniquities. Who livest and reignest with the Father and the Holy Ghost ever one God, world without end. Amen.
