The Catholic Church’s position on birth control is longstanding and relatively recently updated (http://bit.ly/bc-bc), so from that perspective it would be strange for a Jesuit school to offer those sorts of services. The New Catholic Encyclopedia’s article on birth control has a good overview of the history of Church thought on the subject (http://bit.ly/bc-bc2). Professor Massa recently wrote a book on the evolution of theological thinking on it. (http://bit.ly/bc-bc1) You’re asking a practical question, but in this case the theology and history are the reason for the policy.
