Angelus (10 September 1978) http://www.vatican.va/holy_father/john_paul_i/angelus/documents/hf_jp-i_ang_10091978_en.html; in an audience with Philippine bishops on 28 September 1978, he further elaborated: According to tales told by ancient men to attain their political objectives "God is the Father." According to what we really know "God is the Mother."
Context: We are the objects of undying love on the part of God. We know: he has always his eyes open on us, even when it seems to be dark. He is our father; even more he is our mother. He does not want to hurt us, He wants only to do good to us, to all of us. If children are ill, they have additional claim to be loved by their mother. And we too, if by chance we are sick with badness, on the wrong track, have yet another claim to be loved by the Lord.
