Q. Can a couple who’s not married but has a baby together live with each other without it going against the Mormon religion?
In the LDS Church, an unmarried couple is expected to live their lives according to the Law of Chastity. That is, no sexual relations until marriage. Cohabitation, even in abstinence, is discouraged for the inherent temptation and shaky foundation involved.
There are many ways to deal with this situation, and the most recommended is simply to get married. Where a child is already born, you should think not only about your own happiness, but also your partner’s and your baby’s. Doing what’s right for them will, in itself, bring you happiness. Ensuring your child’s future means being a good parent and staying together, even through hard times. From the Proclamation on the Family: ”Children are entitled to birth within the bonds of matrimony, and to be reared by a father and a mother who honor marital vows with complete fidelity.”
Weddings don’t need to be elaborate, expensive affairs, either. Any Mormon bishop will gladly perform the ceremony for free, and will even let you use the local meetinghouse for the services, also free. The only cost is the marriage license you need to obtain from the state. If this sounds like a good idea, get in contact with some local Mormons (the missionaries will be able to introduce you to the right people).
