I think that the point is that we shouldn't make rules based upon something that we cannot know.  The RC Church stipulates celibacy for priests, when it doesn't know whether Jesus was married or not. 

Saundthorp you reply that 'Nowhere in the Gospels does it state He was married either!'  with an exclamation mark as if you are making a hugely important point, when all you are telling us is that we don't know either way (which was the point anyway). It doesn't say in the Gospels whether Jesus had a beard, does the RC church insist that all priests must have beards?, it doesn't say in the Gospels whether Jesus ate meat does the RC church insist that priests should be vegetarians?  We know Jesus wore sandals, does that forbid priests form donning wellies?  The whole thing is so daft.
