Epistle: Galatians i. 11-20

    Lesson from the Epistle of blessed Paul the Apostle to the Galatians. Brethren, I give you to understand that the gospel which was preached by me is not according to man. For neither did I receive it of man, nor did I learn it; but by the revelation of Jesus Christ. For you have heard of my conversation in time past in the Jews' religion: how that beyond measure I persecuted the Church of God, and wasted it; and I made progress in the Jews' religion above many of my equals in my own nation, being more abundantly zealous for the traditions of my fathers. But when it pleased Him, who separated me from my mothers' womb, and called me by His grace, to reveal His Son in me, that I might preach Him among the Gentiles, immediately I condescended not to flesh and blood. Neither went I to Jerusalem to the apostles who me: but I went into Arabia, and again I returned to Damascus. Then, after three years, I went to Jerusalem to see Peter, and I tarried with him fifteen days; but other of the apostles I saw none, saving James the brother of the Lord. Now the things which I write to you, behold before God I lie not.

Gradual: Galatians ii. 8-9; 1 Corinthians xv. 10

    He who wrought in Peter to the apostleship, wrought in me also among the Gentiles; and they knew the grace of God, which was given to me. ℣. The grace of God in me hath not been void; but His grace always remaineth in me.

Alleluia

    Alleluia, alleluia. ℣. Holy apostle Paul, preacher of truth and doctor of the Gentiles, intercede for us. Alleluia.

Gospel: Matthew x. 16-22

    + Continuation of the holy Gospel according to St. Matthew. At that time, Jesus said to His disciples: Behold I send you as sheep in the midst of wolves. Be ye therefore wise as serpents, and simple as doves. But beware of men: for they will deliver you up in councils, and they will scourge you in their synagogues. And you shall be brought before governors, and before kings, for My_sake, for a testimony to them and to the Gentiles. But when they shall deliver you up, take no thought how, or what, to speak; for it shall be given you in that hour what to speak: for it is not you that speak, but the Spirit of your Father that speaketh in you. The brother also shall deliver up the brother to death, and the father the son; and the children shall rise up against the parents, and shall put them to death; and you shall be hated by all men for My name's sake: but he that shall persevere to the end, he shall be saved.

Offertory: Psalms cxxxviii. 17

    To me Thy friends, O God, are made exceedingly honorable; their principality is exceedingly strengthened.
