But it is not appropriate that in lawful matrimony any more should be than two alone, to be joined together under one yoke of wedlock.
For the use of many wives, which our fathers usurped without any blame, may not stablish polygamy for a law among us at these days. The time of correction is now come to light, and Messiah now is come into the world, who teacheth all rightly, and reformeth things amiss.
He therefore hath reduced wedlock to the first prescribed rule and law of matrimony. “Two,” saith the Lord, “shall be one flesh.” And the apostle saith: “Let every man have his own wife, and every woman her own husband.”
The multitude of Solomon’s concubines therefore appertain not to us. We have not to follow the example of Jacob, who married two sisters.
For Christians, even marriage takes its cue from Christ and not from culture. For Christians, marriage consists of the joining together of one man and one woman. Period.
But what about divorce? Bullinger, along with the rest of the Reformers, frowned on it, though they saw it as a concession to the weakness of many. Still, the divorced were not free to remarry. Period.
But what if the spouse dies? Bullinger writes
And yet, notwithstanding, the word of truth condemneth not the second, third, or many marriages which a man maketh, when his wife is deceased.
Marriage, for Christians, means something more than it does for the larger society. The culture may root like pigs in the trough but Christians are called to a better, less porcine, life.
