"It is the privilege of married couples who are able to bear children to provide mortal bodies for the spirit children of God, whom they are then responsible to nurture and rear. The decision as to how many children to have and when to have them is extremely intimate and private and should be left between the couple and the Lord. Church members should not judge one another in this matter.
Married couples should also understand that sexual relations within marriage are divinely approved not only for the purpose of procreation, but also as a way of expressing love and strengthening emotional and spiritual bonds between husband and wife."
Not a single word discouraging birth control, but an emphasis that sexual relations are divinely approved and not only for the purposes of procreation....
