There seems to be some misunderstanding of the instructions given concerning the issuance of temple recommends to wives of nonmembers of the Church. In the latest handbook, page 132, is found the following paragraph pertaining to this subject: Under no circumstances is a recommend to the temple to be issued to a wife whose husband is not a member of the Church. Experience has shown that the results of giving endowments to women whose husbands are not members of the Church have led to regrettable and unfortunate conditions. The question has arisen as to whether this restriction applies to women who are married to non-members but who have taken out their endowments before this rule was given. It should be understood that the rule applies specifically to those who are seeking their own endowments. Women who have previously been in the temple and who are worthy, though their husbands may be non-members, may still be granted the privilege to go through the temple.
