"Rejecting both lifelong celibacy and contraception, classic Protestant theology required family-centered and child-rich pastors. When those clerical leaders, in the privacy of their bedrooms, broke faith with their tradition, when pastors and their wives consciously limited their families, the Protestant opposition to contraception faced a crisis. Typical of a less radical development was the 1981 decision of the Missouri Synod’s Commission on Theology and Church Relations, which argued that although “Be fruitful” is “both a command and a mandate,” “in the absence of Scriptural prohibition” contraception was acceptable “within a marital union which is, as a whole, fruitful.” And if contraception is acceptable, “we will also recognize that sterilization may under some circumstances be an acceptable form of contraception.”"
