“Our Mother is to us in diverse manners working: in whom our parts are kept undisparted. For in our Mother Christ we profit and increase, and in Mercy He reformeth us and restoreth, and, by the virtue of His Passion and His Death and Uprising, oneth us to our Substance. Thus worketh our Mother in Mercy to all His children which are to Him yielding and obedient.”

Summations, Chapter 57
Variant: In Christ our two natures are united.
Context: I saw that our nature is in God whole: in which He maketh diversities flowing out of Him to work His will: whom Nature keepeth, and Mercy and Grace restoreth and fulfilleth. And of these none shall perish: for our nature that is the higher part is knit to God, in the making; and God is knit to our nature that is the lower part, in our flesh-taking: and thus in Christ our two natures are oned.

Summations, Chapter 60
Context: This fair lovely word Mother, it is so sweet and so close in Nature of itself that it may not verily be said of none but of Him; and to her that is very Mother of Him and of all. To the property of Motherhood belongeth natural love, wisdom, and knowing; and it is good: for though it be so that our bodily forthbringing be but little, low, and simple in regard of our spiritual forthbringing, yet it is He that doeth it in the creatures by whom that it is done. The Kindly, loving Mother that witteth and knoweth the need of her child, she keepeth it full tenderly, as the nature and condition of Motherhood will. And as it waxeth in age, she changeth her working, but not her love. And when it is waxen of more age, she suffereth that it be beaten in breaking down of vices, to make the child receive virtues and graces. This working, with all that be fair and good, our Lord doeth it in them by whom it is done: thus He is our Mother in Nature by the working of Grace in the lower part for love of the higher part. And He willeth that we know this: for He will have all our love fastened to Him. And in this I saw that all our duty that we owe, by God’s bidding, to Fatherhood and Motherhood, for God’s Fatherhood and Motherhood is fulfilled in true loving of God; which blessed love Christ worketh in us. And this was shewed in all and especially in the high plenteous words where He saith: It is I that thou lovest.

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.
