If they vowed they would not marry, then they shouldn't marry.

If the Pope mandates they, as priests, cannot marry, then it should be followed, as well.

Eastern Rite Catholics have married clergy along the lines of Orthodox Greek Rite practice and yet they are fully Catholic (the so called Uniates) and I also think this is allowed among the Coptic Rite Catholics and other Eastern Rite Catholics.

So to be correct, Latin Rite Catholic clergy are the only Catholic clergy forbidden to marry though this is in violation of the rulings of the Ecumenical Council on married clergy (though I forget which one).

Based on what? From whence does the pope get that authority? I mean, can you imagine Saint Peter telling another apostle he couldn't marry?
