The Collect
Everlasting God, you so kindled the flame of holy love in the heart of blessed Catherine of Siena, as she meditated on the passion of your Son our Savior, that she devoted her life to the poor and the sick, and to the peace and unity of the Church: Grant that we also may share in the mystery of Christ's death, and rejoice in the revelation of his glory; who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.

First Reading
1 John 1:5-2:2
This is the message we have heard from the Son and proclaim to you, that God is light and in him there is no darkness at all. If we say that we have fellowship with him while we are walking in darkness, we lie and do not do what is true; but if we walk in the light as he himself is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he who is faithful and just will forgive us our sins and cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us.

My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous; and he is the atoning sacrifice for our sins, and not for ours only but also for the sins of the whole world.

5

Your love, O LORD, reaches to the heavens, *
     and your faithfulness to the clouds.

6

Your righteousness is like the strong mountains,
your justice like the great deep; *
     you save both man and beast, O LORD.

7

How priceless is your love, O God! *
     your people take refuge under the shadow of your wings.

8

They feast upon the abundance of your house; *
     you give them drink from the river of your delights.

9

For with you is the well of life, *
     and in your light we see light.

10

Continue your loving-kindness to those who know you, *
     and your favor to those who are true of heart.

or

Psalm 16:5-11    
Conserva me, Domine

5

O LORD, you are my portion and my cup; *
     it is you who uphold my lot.

6

My boundaries enclose a pleasant land; *
     indeed, I have a goodly heritage.

7

I will bless the LORD who gives me counsel; *
     my heart teaches me, night after night.

8

I have set the LORD always before me; *
     because he is at my right hand I shall not fall.

9

My heart, therefore, is glad, and my spirit rejoices; *
     my body also shall rest in hope.

10

For you will not abandon me to the grave, *
     nor let your holy one see the Pit.

11

You will show me the path of life; *
     in your presence there is fullness of joy,
     and in your right hand are pleasures for evermore.
