“And Jesus answering, said to them: You err, not knowing the Scriptures, nor the power of God. For in the resurrection they shall neither marry, nor be given in marriage: but shall be as the angels of God in heaven. But concerning the resurrection of the dead, have you not read that which was spoken by God, saying to you: I am the God of Abraham, and the God of Isaac, and the God of Jacob: He is not the God of the dead, but of the living.” (Gospel according to St. Matthew xxii, 29-32)

“And behold there was a man in Jerusalem named Simeon… and the Holy Ghost was in him… And when his parents brought in the child Jesus… He also took him into his arms, and blessed God, and said: Now thou dost dismiss thy servant, O Lord, according to thy word, in peace: Because my eyes have seen thy salvation, A light to the revelation of the Gentiles, and the glory of thy people, Israel… And Simeon… said to Mary, his mother: Behold, this child is set for the ruin, and for the resurrection of many in Israel, and for a sign which shall be contradicted. And thy own soul a sword shall pierce, that out of many hearts thoughts may be revealed.” (Gospel according to St. Luke ii, 25-35)

“Whosoever will be dissolved and be with Christ, let him come into the Temple, let him come to Jerusalem, let him wait for the Lord’s Christ, let him take hold on the Word of God, let him embrace it with good works… Behold how the Lord’s Birth doth overflow with abounding grace for all, and prophecy is not denied to the just, but to the unbelieving. Behold, Simeon prophesieth that the Lord Jesus Christ is come for the fall and rising again of many; yea, He shall separate the just from the unjust by their deserts, and according as our work shall be, so shall the true and righteous Judge command us to be punished or rewarded.” (St. Ambrose, in the Readings for Matins on the Feast of the Purification of Our Lady)

Despite the polemical title of the text, it has an irenic tone and content. Rather than directly assailing the ideas of the schismatic Eastern churches, it demonstrates that the pre-Photian sources of Eastern theology affirm the teaching of the Catholic Church on points disputed by the schismatic Eastern churches. See James Likoudis’ essay “St. Thomas Aquinas, Defender of the Papacy and the Unity of the Church”.] [Note 2. In his essay “St. Thomas Aquinas, Papal Supremacy, and the Witness of the Eastern Churches in the First Millennium”, James Likoudis discussed objections to St. Thomas’ citations of the Fathers.]
