DR Squared: Memorial Of Saint Ambrose, Bishop And Doctor Of The Church

First Reading:  Ephesians 3:8-12

To me, the least of all the saints, is given this grace, to preach among the Gentiles, the unsearchable riches of Christ, And to enlighten all men, that they may see what is the dispensation of the mystery which hath been hidden from eternity in God, who created all things:  That the manifold wisdom of God may be made known to the principalities and powers in heavenly places through the church, According to the eternal purpose, which he made, in Christ Jesus our Lord:  In whom we have boldness and access with confidence by the faith of him.

Responsorial Psalm:  Ps 89 (88):2; V. 2-3, 4-5, 21-22, 25 and 27

R. The mercies of the Lord I will sing for ever.

V. The mercies of the Lord I will sing for ever. I will shew forth thy truth with my mouth to generation and generation.

     For thou hast said: Mercy shall be built up for ever in the heavens: thy truth shall be prepared in them.

V.  I have made a covenant with my elect: I have sworn to David my servant:

     Thy seed will I settle for ever. And I will build up thy throne unto generation and generation.

V. I have found David my servant: with my holy oil I have anointed him.

    For my hand shall help him: and my arm shall strengthen him.

V. And my truth and my mercy shall be with him: and in my name shall his horn be exalted.

    He shall cry out to me: Thou art my father: my God, and the support of my salvation. 

Gospel Reading:  John 10:11-16

I am the good shepherd. The good shepherd giveth his life for his sheep. But the hireling, and he that is not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and flieth: and the wolf catcheth, and scattereth the sheep:  And the hireling flieth, because he is a hireling: and he hath no care for the sheep. I am the good shepherd; and I know mine, and mine know me. As the Father knoweth me, and I know the Father: and I lay down my life for my sheep. And other sheep I have, that are not of this fold: them also I must bring, and they shall hear my voice, and there shall be one fold and one shepherd.
