John 21:15-17
If thou lovest me, Simon Peter, feed my lambs, feed my sheep. (Allelúja, allelúja.)
Ps 29:2
I will extol thee, O Lord, for thou hast upheld me: and hast not made my enemies to rejoice over me.
Glory Be to the Father…
If thou lovest me, Simon Peter, feed my lambs, feed my sheep. (Allelúja, allelúja.)

O God, Who behold how we fail in our weakness, mercifully restore us to Your love through the examples of Your Saints.
Through our Lord…

Lesson from the first letter of St Peter the Apostle
1 Pet 5:1-4; 5:10-11.
Dearly beloved brethren: The ancients therefore that are among you, I beseech, who am myself also an ancient, and a witness of the sufferings of Christ: as also a partaker of that glory which is to be revealed in time to come: Feed the flock of God which is among you, taking care of it, not by constraint, but willingly, according to God: not for filthy lucre's sake, but voluntarily: Neither as lording it over the clergy, but being made a pattern of the flock from the heart. And when the prince of pastors shall appear, you shall receive a never fading crown of glory. But the God of all grace, who hath called us into his eternal glory in Christ Jesus, after you have suffered a little, will himself perfect you, and confirm you, and establish you. To him be glory and empire for ever and ever. Amen.

Ps 106:32; 106:31
And let them exalt him in the church of the people: and praise him in the chair of the ancients.
℣. Let the mercies of the Lord give glory to him, and his wonderful works to the children of men. Allelúja, allelúja.
Matt 16:18
And I say to thee: That thou art Peter; and upon this rock I will build My Church. Allelúja.

Continuation ☩ of the Holy Gospel according to Matthew
Matt 16:13-19
In that time: Jesus came into the quarters of Caesarea Philippi: and he asked his disciples, saying: Whom do men say that the Son of man is? But they said: Some John the Baptist, and other some Elias, and others Jeremias, or one of the prophets. Jesus saith to them: But whom do you say that I am? Simon Peter answered and said: Thou art Christ, the Son of the living God. And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven. And I say to thee: That 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 to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven.

Jer 1:9-10
Behold I have given my words in thy mouth: Lo, I have set thee over the nations, and over the kingdoms, to root up, and pull down, and to waste, and to destroy, and to build, and to plant. (Allelúja.)

May this sacrificial offering help to cleanse us of our sins, O Lord, and to assure us of Your everlasting salvation.
Through our Lord…

Common
It is truly meet and just, and profitable unto salvation, that we should at all times, and in all places, give thanks to Thee, O Holy Lord, Father Almighty, eternal God, through Christ, our Lord. Through whom the Angels praise Thy Majesty, the Dominions adore it, the Powers are in awe. Which the heavens and the hosts of heaven together with the blessed Seraphim joyfully do magnify. And do Thou command that it be permitted us to join with them in confessing Thee, while we say with lowly praise:

Matt 16:18
Thou art Peter; and upon this rock I will build My Church, and the gates of hell shall not prevail against it. (Allelúja.)

We beseech You, almighty God, that these consecrated gifts may cleanse us of our sins and by their effect make us lead holy lives.
Through our Lord…
