Of his Letters of Doctrine.
Altho' S. Isidore hath not professedly treated of any Doctrine of Religion, yet in many of his Letters we find them very strongly confirmed and proved. He shews, That the Heathen Religion hath evident Marks of Falshood, l. 1. 95. l. 4. 27, 29, 30, &c. And that Christianity hath all the Signs of Truth, and opposes those who accuse it of Novelty, l. 2. 46. He affirms, That if we do but compare the Holy Scriptures with the Heathen-writers, we may soon discern on which side the true Religion is, l. 1. 21. That the former contain sublime Truths, which beget Reverence, whereas the latter are full of Fables and despicable Fooleries and Cheats, l. 2. 4, 5. Among the Proofs of the Christian Religion he forgets not to insert that of the confirmation of the Gospel by Miracles, and the destruction of Paganism, l. 1. 271. He confutes the Jews in several places, not only by demonstrating, That the Prophecies of the Messias are fulfilled in Jesus Christ, but al∣so by confirming the truth of the Conception of Jesus Christ in the Womb of the Virgin, l. 1. 141. l. 4. 17. He proves, That God hath created Angels, Men and all Beings, l. 1. 343. That all Things are over-ruled by Providence, and not by the influences of the Stars, or by Fate, l. 3. 135, 154, 191. That Things do not come to pass, because God foreknows them or foretells them, but God foreknows and foretells them because they will so happen, l. 1. 56. He explains the Myste∣ries of the Trinity and Incarnation in so many Letters, that it is needless to cite them all. Among others, these are worthy of our Consideration about the Trinity, l. 1. 67, 138, 139, 327. l. 4. 99. About the Incarnation, l. 1. 323, 403. He confutes the Error of the Arrians, l. 1. 246, 353. l. 4. 31, 334. and of the Sabellians, l. 3. 247. He proves the God-head of the Holy Ghost, l. 1. 20, 60, 97, 109, 499, 500, &c. He condemns the Error of the Nestorians, and shews that the name of the Mother of God ought to be given to the Virgin Mary, l. 1. 54. He also opposes those, who confounded the two Natures, as well as the Manichees, who asserted, That the Flesh which appeared in Jesus Christ, was a mere Phantom, l. 1. 124, 323, 102, 303. He refutes the Marcion∣ites, l. 1. 11. the Manichees, l. 4. 13. the Montanists, l. 1. 242. to the 246. and the Novatians, l. 1. 100, 338. He maintains the perpetual Virginity of Mary, both before and after her Con∣ception, l. 1. 23. He is of Opinion, That Jesus Christ came out of her Womb, as well as out of the Sepulchre, without opening the Passage, l. 1. 404. He proves the Soul to be Immortal, l. 3. 295. l. 4. 125. But he confutes the Doctrine of Origen about the eternal Praeexistence of Souls, l. 4. 163. He also disproves the Opinion of those who believed, That the Soul is part of the Substance of God himself, l. 4. 124. He shews, That the Resurrection of the Body is certain, but the manner of it and time, is uncertain, l. 1. 284. l. 2. 43. He holds, That after the Resurre∣ction, the Bodies of the damned shall be Spiritual, as well as the Bodies of the blessed; that is to
