John Chrysostom
Yet when Paul bids us obey our parents in all things, we are not to marvel; for we are only to obey in such things as are not hurtful to our piety to God. It is holy to render them every other honour, but when they demand more than is due, we ought not to yield. This is likewise agreeable to the Old Testament; in it the Lord commands that all who worshipped idols, should not only be held in abhorrence, but should be stoned. And in Deuteronomy it is said, He who saith to his father and his mother, I know you not; and to his brethren, Ye are strangers; he hath kept thy saying. (Deut. 33:9.)
Then that those to whom the love of God is preferred should not be offended thereat, He leads them to a higher doctrine. Nothing is nearer to a man than his soul, and yet He enjoins that this should not only be hated, but that a man should be ready to deliver it up to death, and blood; not to death only, but to a violent and most disgraceful death, namely, the death of the cross; therefore it follows, And whoso taketh not up his cross and followeth me, is not worthy of me. He had as yet said nothing to them respecting his own sufferings, but instructs them in the meanwhile in these things, that they may the more readily receive His words concerning His passion.
Because these commands seemed burdensome, He proceeds to shew their great use and benefit, saying, He that findeth his life shall lose it. As much as to say, Not only do these things that I have inculcated do no harm, but they are of great advantage to a man; and the contrary thereof shall do him great hurt—and this is His manner every where. He uses those things which men’s affections are set upon as a means of bringing them to their duty. Thus: Why are you loath to contemn your life? Because you love it? For that very reason contemn it, and you will do it the highest service.
