prescrib'd to his Souldiers, related in B. IV. and the Admonition he gave a Covetous Man of his Court, which is to be found Ch. 30. of the same Book: But doubtless the most considerable of his Monuments, is, that great Oration which he made to the Convention of the Saints, translated by Eusebius into Greek, and annexed to his Life. The Preface of this Oration is about the Feast of Easter, the Goodness of our Saviour, and the Ingratitude of Men; but he concludes it with an Apostrophe to the Church. In the Bo∣dy of this Discourse, he disputes against Idolatry and the multiplicity of Gods; and shows that there is but one only true God, the Creator of all things, and the Father of the Word, who is begotten of Him, tho' the Father suffer no Diminution by it, and who is united to Him: He confutes Destiny, establishes Providence and Free-Will, and overthrows the Errors of the Philosophers: He discovers the Advantages which Mankind receiv'd by the Incarnation of the Son of God, and shows that his Coming was foretold by the Prophets, to whose Authority he adds the Prediction of the Sybils, which he endeavours to verifie by the Testimony of Virgil: He describes the unhappy death of those Emperors who persecuted the Church, and finishes this Discourse with saying, That we ought to attribute all the Good we do to God, and be∣fore we undertake any thing, always to implore his Aid by Prayer, as being the Fountain of all Good. The whole Discourse is Sublime, and worthy of the Majesty of such an Emperour as Constantine was.
