This is a very strange saying, and discovers to us both the imperfect state of Christ’s disciples, and also the tyranny of a sinful practice grown up into a custom. The Jews had assumed a liberty of turning their wives out of doors upon every light and trivial offence or dislike; the disciples think, if this licentiousness may not be allowed it is not good to marry. So a holy institution of God, ordained for the propagation of mankind, for the restraint of extravagant lust, and for the solace and comfort of man’s life, should be despised, rather than those unquiet lusts and corruptions mortified, the mortification of which would have made those irregular separations both needless and undesirable. Surely they should rather have said, If the case of a man be so with his wife, then both husbands and wives had need to learn to deny themselves, to comply each with another, to silence their brutish and boisterous passions, that, being the same flesh, they might also have one and the same spirit, and not be like a diseased piece of flesh, where humours so quarrel that one piece need be cut off to preserve the other. But the best of men have their infirmities; and, as the Hebrews said, Spiritus Dei non semper tangit corda prophetarum, The Spirit of God was not always upon the hearts of the prophets; so it is as true, Spiritius Dei non semper et ubique tangit corda fidelium, All that the saints say is not gospel. Their flesh hath its turn to speak, as well as the Spirit in them. A sinful liberty conceded, indulged, or connived at, by the laws, or by the rulers of a church or place where we live, for a long time, is not easily restrained, and even good men may for a time be carried away with the error of it, so as they cannot discern it, be convinced of it, or be brought clear of it to a conformity to the will of God.
