CCC 2214 The divine fatherhood is the source of human fatherhood;1 this is the foundation of the honor owed to parents. The respect of children, whether minors or adults, for their father and mother2 is nourished by the natural affection born of the bond uniting them. It is required by God’s commandment.3
