Calvin Institutes on the church:
“I will begin with the Church, into whose bosom God is pleased to collect his
children, not only that by her aid and ministry they may be nourished so long as they
are babes and children, but may also be guided by her maternal care until they grow
up to manhood, and, finally, attain to the perfection of faith. What God has thus
joined, let not man put asunder (Mark 10:9): to those to whom he is a Father, the
Church must also be a mother." [4.1.1]
Proverbs 23:22, "Hearken unto thy father that begat thee, and despise not thy mother when she is old."
