4:5. Behold, I will send you Elias the prophet, before the coming of the great and dreadful day of the Lord.
4:6. And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers: lest I come, and strike the earth with anathema.
He shall turn the heart, etc... By bringing over the Jews to the faith of Christ, he shall reconcile them to their fathers, viz., the partiarchs and prophets; whose hearts for many ages have been turned away from them, because of their refusing to believe in Christ.-Ibid. With anathema... In the Hebrew, Cherem, that is, with utter destruction.
Book 45 1 Machabees
THE FIRST BOOK OF MACHABEES
These books are so called, because they contain the history of the people of God under the command of Judas Machabeus and his brethren: and he, as some will have it, was surnamed Machabeus, from carrying in his ensigns, or standards, those words of Exodus 15.11, Who is like to thee among the strong, O Lord: in which the initial letters, in the Hebrew, are M. C. B. E. I. It is not known who is the author of these books. But as to their authority, though they are not received by the Jews, saith St. Augustine, (lib. 18, De Civ. Dei, c. 36,) they are received by the church: who, in settling her canon of the scriptures, chose rather to be directed by the tradition she had received from the apostles of Christ, than by that of the scribes and Pharisees. And as the church has declared these two Books canonical, even in two general councils, viz., Florence and Trent, there can be no doubt of their authenticity.
