XII | Of the State of Matrimony.
We confess that there is in the church of God an honorable state of matrimony, of two free, believing persons, in accordance with the manner after which God originally ordained the same in paradise, and instituted it himself with Adam and Eve, and that the Lord Christ did away and set aside all the abuses of marriage which had meanwhile crept in, and referred all to the original order, and thus left it. Gen. 1:27; Mark 10:4.
In this manner the apostle Paul also taught and permitted matrimony in the church, and left it free for every one to be married, according to the original order, in the Lord, to whomsoever one may get to consent. By these words, in the Lord, there is to be understood, we think, that even as the patriarchs had to marry among their kindred or generation, so the believers of the New Testament have likewise no other liberty than to marry among the chosen generation and spiritual kindred of Christ, namely such, and no others, who have previously become united with the church as one heart and soul, have received one baptism, and stand in one communion, faith, doctrine and practice, before they may unite with one another by marriage. Such are then joined by God in his church according to the original order; and this is called, marrying in the Lord. 2 Cor. 7:2; 1 Cor. 9:5; Gen. 24:4; 28:2; 1 Cor. 7:39.
