1. Several centuries ago, the Catholic Church decided that priests etc. had to be male and unmarried.
So what happened to all the priests etc. who were married when the rule was introduced? Surely they can't have all got divorced, because that's against the rules as well.
2. A couples of centuries later, lots of Christians left the Catholic church to form their own 'protestant' churches, for different reasons in different countries.
The power to declare somebody a saint has been the sole preserve of The Pope since about AD 400. For some reason, most protestant churches recognised all saints who had been declared saints before they broke away, but not those afterwards, and in the meantime, some protestant churches have had their own system for declaring somebody to be a saint, but that person only counts as a saint in his own territory.
So for example, you can see both Catholic and protestant churches called "St John" or "St Peter" (old saints), but after that, the systems have diverged. You won't see a Catholic churn called after a modern protestant saint or a protestant church called after a modern Catholic saint.
Can anybody reconcile this with any underlying logic?
