Tertullian
Patristic
c. A.D. 150–220
“Our Lord frequently proclaimed God as a Father to us. He even gave us an instruction "that we call no one on earth father, but the Father whom we have in the heavens." So, in praying ["Our Father"] we are likewise obeying the precept. Those who recognize their Father are blessed! This is the reproach that is brought against Israel, to which the Spirit attests heaven and earth, saying, "I have begotten children, and they have not recognized me."”
