Who now rejoice in my sufferings for you, and fill up those things that are wanting of the sufferings of Christ, in my flesh, for his body, which is the church: Whereof I am made a minister according to the dispensation of God, which is given me towards you, that I may fulfill the word of God: The mystery which hath been hidden from ages and generations, but now is manifested to his saints, To whom God would make known the riches of the glory of this mystery among the Gentiles, which is Christ, in you the hope of glory. Whom we preach, admonishing every man, and teaching every man in all wisdom, that we may present every man perfect in Christ Jesus. Wherein also I labour, striving according to his working which he worketh in me in power.
Responsorial Psalm: Psalm 34 (33):5b; V. 2-3, 4-5, 6-7, 8-9
R. (A)nd he delivered me from all my troubles.V. I will bless the Lord at all times,his praise shall be always in my mouth.In the Lord shall my soul be praised:let the meek hear and rejoice.V. O magnify the Lord with me;and let us extol his name together.I sought the Lord, and he heard me;and he delivered me from all my troubles.V. Come ye to him and be enlightened:and your faces shall not be confounded.This poor man cried, and the Lord heard him:and saved him out of all his troubles.V. The angel of the Lord shall encamp round about them that fear him:and shall deliver them.O taste, and see that the Lord is sweet:blessed is the man that hopeth in him.
Gospel Reading: John 17:20-26
And not for them only do I pray, but for them also who through their word shall believe in me; That they all may be one, as thou, Father, in me, and I in thee; that they also may be one in us; that the world may believe that thou hast sent me. And the glory which thou hast given me, I have given to them; that they may be one, as we also are one: I in them, and thou in me; that they may be made perfect in one: and the world may know that thou hast sent me, and hast loved them, as thou hast also loved me. Father, I will that where I am, they also whom thou hast given me may be with me; that they may see my glory which thou hast given me, because thou hast loved me before the creation of the world. Just Father, the world hath not known thee; but I have known thee: and these have known that thou hast sent me. And I have made known thy name to them, and will make it known; that the love wherewith thou hast loved me, may be in them, and I in them.
