De Abrahamo

In the second place, though it was not the custom in the land in which he was living, as perhaps it is among some nations, to offer human sacrifices, and custom, by its frequency, often removes the horror felt at the first appearance of evils, he himself was about to be the first to set the example of a novel and most extraordinary deed, which I do not think that any human being would have brought himself to submit to, even if his soul had been made of iron or of adamant; for as some one has said, —

In the second place, after he had become the father of this his only legitimate son, he, from the moment of his birth, cherished towards him all the genuine feelings of affection, which exceeds all modest love, and all the ties of friendship which have ever been celebrated in the world.

There was added also, this most forcible charm of all, that he had become the father of this son not in the prime of his life, but in his old age. For parents become to a certain degree insane in their affection for children of their old age, either from the circumstance of their having been wishing for their birth a long time, or else because they have no longer any hope that they shall have any more; nature having taken her stand there as at the extreme and furthest limit.

Now there is nothing unnatural or extraordinary in devoting one child to God out of a numerous family, as a sort of first fruits of all one’s children, while one still has pleasure in those who remain alive, who are no small comfort and alleviation of the grief felt for the one who is sacrificed. But the man who gives the only beloved son that he is possessed of performs an action beyond all powers of language to praise, as he is giving nothing to his own natural affection, but inclining with his whole will and heart to show his devotion to God.
