A Nun's Silence

A Roman Catholic nun being interviewed today Sunday at lunchtime on BBC Radio 4. Sister Catherine Cowley. Prior to her vocation, she was in banking. Now she is based at the Convent of the Assumption, in Kensington Square. (My old Parish. She was almost a parishioner of mine. Huh!)
Sister Catherine, who does not wear a wimple or any such demode' religious trappings, sounds quite sensible. She spoke many reasonable and, yes, wise things. About the market and ethics. How the market cannot claim to be immune from ethical criteria. Greed. The common good. And so on.
There is nothing in what Sister Catherine said that I could fault. In fact, I agree with what she said. Still, there is something that bothered me about her. Not about anything she said but what she did NOT say. What was that?
She did not, even once, mention God or Christ.
Maybe I am being unfair, extreme, obstreperous (well, that me, folks!) but this I know: a nun who does not mention God is no good.
