DR Squared: Optional Memorial Of Saint Cyril Of Jerusalem, Bishop And Doctor Of The Church

First Reading:  1 John 5:1-5

Whosoever believeth that Jesus is the Christ, is born of God. And every one that loveth him who begot, loveth him also who is born of him. In this we know that we love the children of God: when we love God, and keep his commandments. For this is the charity of God, that we keep his commandments: and his commandments are not heavy. For whatsoever is born of God, overcometh the world: and this is the victory which overcometh the world, our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?

Responsorial Psalm:  Psalm 19 (18):10b or John 6:64; V. Psalm 8, 9, 10, 11

R.  (T)he judgments of the Lord are true, justified in themselves.

or

R.  The words that I have spoken to you, are spirit and life.

V.  The law of the Lord is unspotted, converting souls:

      the testimony of the Lord is faithful, giving wisdom to little ones.

V.  The justices of the Lord are right, rejoicing hearts:

      the commandment of the Lord is lightsome, enlightening the eyes.

V.  The fear of the Lord is holy, enduring for ever and ever:

      the judgments of the Lord are true, justified in themselves.

V.  More to be desired than gold and many precious stones:

      and sweeter than honey and the honeycomb.  

Gospel Reading:  John 15:1-8

I am the true vine; and my Father is the husbandman. Every branch in me, that beareth not fruit, he will take away: and every one that beareth fruit, he will purge it, that it may bring forth more fruit. Now you are clean by reason of the word, which I have spoken to you. Abide in me, and I in you. As the branch cannot bear fruit of itself, unless it abide in the vine, so neither can you, unless you abide in me. I am the vine: you the branches: he that abideth in me, and I in him, the same beareth much fruit: for without me you can do nothing. If any one abide not in me, he shall be cast forth as a branch, and shall wither, and they shall gather him up, and cast him into the fire, and he burneth. If you abide in me, and my words abide in you, you shall ask whatever you will, and it shall be done unto you. In this is my Father glorified; that you bring forth very much fruit, and become my disciples.
