Excellent article in the Washington Post, by Fr. Willam Blazek, SJ.
I particularly liked this:
"Final point, we kill the Church when, in ignorance, we hold it up to ridicule. Last Spring, I asked several medical students in a seminar whether they rejected Catholic teachings regarding reproduction and artificial contraception. Several raised their hands. I prompted them to articulate the position and to give their critique of it. Conversation languished for some while. None in that group of graduating physicians had an answer, yet these well-educated role models were willing to publicly disagree with an argument they could not explain."
