Collect

℣. The Lord be with you.
℟. And with thy spirit.
Let us pray.
O God, Whose only-begotten Son appeared in the substance of our flesh, grant, we pray You, that we who acknowledge His outward likeness to us may deserve to be inwardly refashioned in His image.
Who livest and reignest with God the Father, in the unity of the Holy Spirit, God, world without end.
℟. Amen

From the Holy Gospel according to John
John 1:29-34
At that time, John saw Jesus coming to him, and he saith: Behold the Lamb of God, behold him who taketh away the sin of the world. And so on.

Homily by St. Augustine, Bishop of Hippo.
6th Tract on John
John knew Jesus even before He came to be baptized of him in Jordan, as we perceive by the words I have need to be baptized of thee, and comest Thou to me? Behold, how he knew that He was the Lord, how he knew that He was the Son of God! How do we prove that he knew that He it was Who should baptize with the Holy Ghost? Before the Lord came to the river, when many betook themselves to John to be baptized of him, the Baptist said I indeed baptize you with water but One Mightier than I cometh; the latchet of Whose shoes I am not worthy to unloose He shall baptize you with the Holy Ghost and with fire. Luke iii. 16. Behold, John knew this also.

Post Communion
P. The Lord be with you.
S. And with thy spirit.
Let us pray.
We pray You, O Lord, to go before us at all times and in all places with Your heavenly light, that we may discern with clear sight and receive with the right disposition the sacrament of which You have willed that we should partake.
Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, God, world without end.
℟. Amen.
