First Reading: 1 John 2:29-3:6
29 If you know, that he is just, know ye, that every one also, who doth justice, is born of him.
1 Behold what manner of charity the Father hath bestowed upon us, that we should be called, and should be the sons of God. Therefore the world knoweth not us, because it knew not him.
2 Dearly beloved, we are now the sons of God; and it hath not yet appeared what we shall be. We know, that, when he shall appear, we shall be like to him: because we shall see him as he is.
3 And every one that hath this hope in him, sanctifieth himself, as he also is holy.
4 Whosoever committeth sin committeth also iniquity; and sin is iniquity.
5 And you know that he appeared to take away our sins, and in him there is no sin.
6 Whosoever abideth in him, sinneth not; and whosoever sinneth, hath not seen him, nor known him.
Psalm: Psalms 98:1,3cd-4,5-6
1 A psalm for David himself. The Lord hath reigned, let the people be angry: he that sitteth on the cherubims: let the earth be moved.
3 Let them give praise to thy great name: for it is terrible and holy:
4 And the kings honour loveth judgment. Thou hast prepared directions: thou hast done judgment and justice in Jacob.
5 Exalt ye the Lord our God, and adore his footstool, for it is holy.
6 Moses and Aaron among his priests: and Samuel among them that call upon his name. They called upon the Lord, and he heard them:
Gospel: John 1:29-34
29 The next day, John saw Jesus coming to him, and he saith: Behold the Lamb of God, behold him who taketh away the sin of the world.
30 This is he, of whom I said: After me there cometh a man, who is preferred before me: because he was before me.
31 And I knew him not, but that he may be made manifest in Israel, therefore am I come baptizing with water.
32 And John gave testimony, saying: I saw the Spirit coming down, as a dove from heaven, and he remained upon him.
33 And I knew him not; but he who sent me to baptize with water, said to me: He upon whom thou shalt see the Spirit descending, and remaining upon him, he it is that baptizeth with the Holy Ghost.
34 And I saw, and I gave testimony, that this is the Son of God.
