These then, are the two tremendous alternatives: on the one hand the possibility of securing, in all sympathy and tenderness, the laying of that step on which man rises towards his perfection; on the other hand the blight of all sympathy, to be dragged down to earth, and forced to become frivolous and common-place; to lose all zest and earnestness in life, to have heart and life degraded by mean and perpetually-recurring sources of disagreement; these are the two alternatives, and it is the worst of these alternatives which the young risk when they form an inconsiderate union, excusably indeed--because through inexperience; and it is the worst of these alternatives which parents risk--not excusably but inexcusably--when they bring up their children with no higher view of what that tie is, than the merely prudential one of a rich and honourable marriage.
The second decision which the apostle makes respecting another of the questions proposed to him by the Corinthians, is as to the sanctity of the marriage bond between a Christian and one who is a heathen. When Christianity first entered into our world, and was little understood, it seemed to threaten the dislocation and alteration of all existing relationships. Many difficulties arose; such for instance, as the one here started. When of two heathen parties only one was converted to Christianity, the question arose, What in this case is the duty of the Christian? Is not the duty separation? Is not the marriage in itself null and void? as if it were an union between one dead and one living? And that perpetual contact with a heathen, and therefore an enemy of God, is not that in a relation so close and intimate, perpetual defilement? The apostle decides this with his usual inspired wisdom. He decides that the marriage-bond is sacred still. Diversities of religious opinion, even the farthest and widest diversity, cannot sanction separation. And so he decides in the 13th verse, "The woman which hath an husband that believeth not, if he be pleased to dwell with her, let her not leave him." And, "if any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away," v. 12.
Now for us in the present day, the decision on this point is not of so much importance as the reason which is adduced in support of it. The proof which the Apostle gives of the sanctity of the marriage is exceedingly remarkable. Practically it amounts to this;--If this were no marriage, but an unhallowed alliance, it would follow as a necessary consequence that the offspring could not be reckoned in any sense as the children of God; but, on the other hand, it is the instinctive, unwavering conviction of every Christian parent, united though he or she may be to a heathen, "My child is a child of God," or, in the Jewish form of expression, "My child is _clean_." So the apostle says, "the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now they are holy," for it follows if the children are holy in this sense of dedicated to God, and are capable of Christian relationship, then the marriage relation was not unhallowed, but sacred and indissoluble.
