DR Squared: Optional Memorial Of Saint Callistus I, Pope And Martyr

First Reading: 1 Peter 5:1-4

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.

Responsorial Psalm:  Psalm 40 (39):8a and 9a; V. 2 and 4, 7-8a, 8b-9, 10, 11

R.  Then said I, Behold I come. That I should do thy will:

V.  With expectation I have waited for the Lord,

     and he was attentive to me.

     And he put a new canticle into my mouth,

     a song to our God.

V.  Sacrifice and oblation thou didst not desire;

     but thou hast pierced ears for me.

     Burnt offering and sin offering thou didst not require:

     Then said I, Behold I come.

V.  In the head of the book it is written of me

     That I should do thy will:

     O my God, I have desired it,

     and thy law in the midst of my heart.

V.  I have declared thy justice in a great church,

     lo, I will not restrain my lips: O Lord, thou knowest it.

V.  I have not hid thy justice within my heart:

     I have declared thy truth and thy salvation.

     I have not concealed thy mercy

     and thy truth from a great council.

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.
