what God he preaches? For his words are: “Paul, the servant of Jesus Christ, called to be an apostle, set apart to the gospel of God, which He had promised afore by His prophets in the holy Scriptures concerning His Son, who was made of the seed of David according to the flesh, and who was declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead of Christ Jesus our Lord,”[192] etc. Moreover, also the following, “Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen? or saith he it altogether for our sakes? For our sakes, no doubt, this is written, that he that plougheth should plough in hope, and he that thresheth in hope of partaking of the fruits.”[193] By which he manifestly shows that God, who gave the law on our account, _i.e._ on account of the apostles, says, “Thou shalt not muzzle the mouth of the ox that treadeth out the corn;” whose care was not for oxen, but for the apostles, who were preaching the gospel of Christ. In other passages also, Paul, embracing the promises of the law, says, “Honour thy father and thy mother, which is the first commandment with promise; that it may be well with thee, and that thy days may be long upon the land, the good land, which the Lord thy God will give thee.”[194] By which he undoubtedly makes known that the law, and the God of the law, and His promises, are pleasing to him. 3. But as those who uphold this heresy are sometimes accustomed to mislead the hearts of the simple by certain deceptive sophisms, I do not consider it improper to bring forward the assertions which they are in the habit of making, and to refute their deceit and falsehood. The following, then, are their declarations. It is written, that “no man hath seen God at any time.”[195] But that God whom Moses preaches was both seen by Moses himself, and by his fathers before him; whereas He who is announced by the Saviour has never been seen at all by any one. Let us therefore ask them and ourselves whether they maintain that he whom they acknowledge to be God, and allege to be a different God from the Creator, is visible or invisible. And if they shall say that he is visible, besides being proved to go against the declaration of Scripture, which says of the Saviour, “He is the image of the invisible God, the first-born of every creature,”[196] they will fall also into the absurdity of asserting that God is corporeal. For nothing can be seen except by help of form, and size, and colour, which are special properties of bodies. And if God is declared to be a body, then He will also be found to be material, since every body is composed of matter. But if He be composed of matter, and matter is undoubtedly corruptible, then, according to them, God is liable to corruption! We shall put to them a second question. Is matter made, or is it uncreated, _i.e._ not made? And if they shall answer that it is not made, _i.e._ uncreated, we
