These things saith the Amen, the faithful and true witness, who is the beginning of the creation of God: Behold, I stand at the gate, and knock. If any man shall hear my voice, and open to me the door, I will come in to him, and will sup with him, and he with me. To him that shall overcome, I will give to sit with me in my throne: as I also have overcome, and am set down with my Father in his throne. He that hath an ear, let him hear what the Spirit saith to the churches.
Responsorial Psalm: Psalm 23:1-3a, 4, 5, 6
R. The Lord ruleth me: and I shall want nothing.V. The Lord ruleth me: and I shall want nothing.He hath set me in a place of pasture.He hath brought me up, on the water of refreshment:He hath converted my soul.V. For though I should walk in the midst of the shadow of death,I will fear no evils,for thou art with me.Thy rod and thy staff, they have comforted me.V. Thou hast prepared a table before meagainst them that afflict me.Thou hast anointed my head with oil;and my chalice which inebriateth me, how goodly is it!V. And thy mercy will follow meall the days of my life.And that I may dwell in the house of the Lordunto length of days.
Gospel Reading: Luke 22:24-30
And there was also a strife amongst them, which of them should seem to be the greater. And he said to them: The kings of the Gentiles lord it over them; and they that have power over them, are called beneficent. But you not so: but he that is the greater among you, let him become as the younger; and he that is the leader, as he that serveth. For which is greater, he that sitteth at table, or he that serveth? Is it not he that sitteth at table? But I am in the midst of you, as he that serveth: And you are they who have continued with me in my temptations: And I dispose to you, as my Father hath disposed to me, a kingdom; That you may eat and drink at my table, in my kingdom: and may sit upon thrones, judging the twelve tribes of Israel.
