I’ll tell you from experience, it is very bad when a nun tries to act like your mother. My mother died when I was 9 and the nuns at school tried to “mother” me. Unfortunately that is not a job for a woman that has never been married and never had sex.
Mat12:47 But he replied to the man who told him, “Who is my mother, and who are my brothers?” (RSV)
Mat12:48 And stretching out his hand toward his disciples, he said, “Here are my mother and my brothers! (RSV)
Mat12:49 For whoever does the will of my Father in heaven is my brother, and sister, and mother.”
