“Called to give life, spouses share in the creative power and fatherhood of God. Married couples should regard it as their proper mission to transmit life and to educate their children; they should realize that they are cooperating with the love of God the Creator and are, in a certain sense, its interpreters. They will fulfill this duty with a sense of human and Christian responsibility.” (Catechism of the Catholic Church 2367)
