Fulton Confession of Faith/Chapter XXV
1. Marriage is to be between one man and one woman; neither is it lawful for any man to have more than one wife, nor for any woman to have more than one husband at the same time.[1]
2. Marriage was ordained for the mutual help of husband and wife,[2] for the increase of mankind with a legitimate issue,[3] and for preventing uncleanness.[4]
3. It is lawful for all sorts of people to marry, who are able with judgment to give their consent;[5] yet it is the duty of Christians to marry in the Lord;[6] and therefore such as profess the true religion, should not marry with infidels, or idolators; neither should such as are godly, be unequally yoked, by marrying with such as are wicked in their life, or maintain damnable heresy.[7]
4. Marriage ought not to be within the degrees of consanguinity or affinity, forbidden in the Word;[8] nor can such incestuous marriages ever be made lawful, by any law of man or consent of parties, so as those persons may live together as man and wife.[9]
