The rule of the temple is that a woman who marries outside of the Church cannot receive a recommend to go through the temple, because her husband would be very apt to ask her to reveal the temple ordinances and if she refused to do so it would cause contention between them. If she has married a man in the Church, and she desires to receive her endowments, we do not feel that it would be wise for her to receive her endowments before her husband, and hence bishops are told not to give recommendations to wives before their husbands go with them to the temple. If a wife received her endowments before she married[,] she showed her weakness in not keeping her covenants, but still if she afterwards proves herself a staunch Latterday Saint and tries to live as such and has not cast off her garments, we think the bishop may give her a recommend to do work in the temple. However, if she cast off her garments when she married, we do not feel that she should be entitled to receive a recommend to the House of the Lord.
