While
serving as editor for the Improvement Era, the Church's monthly publication
until 1970, Charles W. Penrose wrote the following in the September 1912 issue:
Question 2: Do you believe that Jesus was
married?
Answer: We do not know anything about Jesus
Christ being married. The Church has no authoritative declaration on the
subject. ("Editor's Table," Improvement Era volume 15 no. 11 [1912]:1042; available online here)
