From this it follows that as truly as God is our Father, so truly is God our Mother. Our Father wills, our Mother works, our good Lord the Holy Spirit confirms. And therefore it is our part to love our God in whom we have our being, reverently thanking and praising him for our creation, mightily praying to our Mother for mercy and pity, and to our Lord the Holy Spirit for help and grace. For in these three is all our life….
And so Jesus is our true Mother in nature by our first creation, and he is our true Mother in grace by his taking our created nature. All the lovely works and all the sweet loving offices of beloved motherhood are appropriated to the second person, for in him we have this godly will, whole and safe forever, both in nature and in grace, from his own goodness proper to him.
I understand three ways of contemplating motherhood in God. The first is the foundation of our nature’s creation; the second is his taking of our nature, where the motherhood of grace begins; the third is the motherhood at work. And in that, by the same grace, everything is penetrated, in length and in breadth, in height and in depth without end; and it is all one love….
The mother’s service is nearest, readiest and surest: nearest because it is most natural, readiest because it is most loving, and surest because it is truest.
--Julian of Norwich, Showings (Long Text, chs. 59-60)
