Nice straw man. 

The Church can change her teaching on certain aspects of celibacy--for example--allowing a married clergy.  That is different from allowing clergy to get married. The fact that the author of this article left the priesthood to get married is fine.  That does not entail that the Church can allow those who were ordained to the priesthood prior to being married to get married.

The apostles were married, save John, I think, before Jesus called them to the office.  There is no tradition for someone being called to ordination--then being permitted to marry.  

Of course you missed my point anyway--which wasn't about celibacy.  My point was that--the fact that some people cannot accept church teaching and struggle with it does not entail the Church has to change it.  The Church is not the problem. The teaching of the Church is not the problem.
