The Divine Institutes

I have now confirmed, as I imagine, the things which are thought false and incredible by those who are not instructed in the true knowledge of heavenly learning. But, however, that we may refute those also who are too wise, not without injury to themselves, and who detract from the credit due to divine things, let us disprove their error, that they may at length perceive that the fact ought to have been as we show that it actually was. And although with good judges either testimonies are of sufficient weight without arguments, or arguments without testimonies, we, however, are not content with the one or the other, since we are supplied with both, that we may not leave room for any one of depraved ingenuity either to misunderstand or to dispute on the opposite side.

They say that it was impossible for anything to be withdrawn from an immortal nature. They say, in short, that it was unworthy of God to be willing to become man, and to burden Himself with the infirmity of flesh; to become subject of His own accord to sufferings, to pain, and death: as though it had not been easy for Him to show Himself to men without the weakness incident to a body, and to teach them righteousness (if He so wished) with greater authority, as of one who acknowledged Himself to be God.

For in that case all would have obeyed the heavenly precepts, if the influence and power of God enjoining them had been united with them. Why, then (they say), did He not come as God to teach men? Why did He render Himself so humble and weak, that it was possible for Him both to be despised by men and to be visited with punishment? Why did He suffer violence from those who are weak and mortal? Why did He not repel by strength, or avoid by His divine knowledge, the hands of men?

Why did He not at least in His very death reveal His majesty? But He was led as one without strength to trial, was condemned as one who was guilty, was put to death as one who was mortal. I will carefully refute these things, nor will I permit any one to be in error. For these things were done by a great and wonderful plan; and he who shall understand this, will not only cease to wonder that God was tortured by men, but also will easily see that it could not have been believed that he was God if those very things which he censures had not been done.
