10:15. And how shall they preach unless they be sent, as it is written: How beautiful are the feet of them that preach the gospel of peace, of them that bring glad tidings of good things?
Unless they be sent… Here is an evident proof against all new teachers, who have all usurped to themselves the ministry without any lawful mission, derived by succession from the apostles, to whom Christ said, John 20.21, As my Father hath sent me, I also send you.
10:16. But all do not obey the gospel. For Isaias saith: Lord, who hath believed our report?
10:17. Faith then cometh by hearing; and hearing by the word of Christ.
10:18. But I say: Have they not heard? Yes, verily: Their sound hath gone forth into all the earth: and their words unto the ends of the whole world.
10:19. But I say: Hath not Israel known? First, Moses saith: I will provoke you to jealousy by that which is not a nation: by a foolish nation I will anger you.
10:20. But Isaias is bold, and saith: I was found by them that did not seek me. I appeared openly to them that asked not after me.
10:21. But to Israel he saith: All the day long have I spread my hands to a people that believeth not and contradicteth me.
Romans Chapter 11
God hath not cast off all Israel. The Gentiles must not be proud but stand in faith and fear.
