Your quotes don't add up to any infringement on freedom, since there is nothing compulsory about taking a vow. You do realize this is voluntary celibacy, right?
You do realize that a person who has vowed celibacy, has vowed it to God?
You do realize that a priest who wants out, can do so with permission (be laicized) or without permission (just walk out)?
In the later case, he faces ecclesiatical penalties; but if he's the kind of guy who breaks his vows to God, why would he give two hoots about ecclesiastical penalties? He's still free to be as unfaithful as he wants.
You do realize that the Church also forbids breaking the Marriage vows in a valid marriage, too --- right? Do you think the Church is wrong to frown on the breaking of those voluntary vows?
This is no offense against freedom, since a person freely makes vows, preistly ones, or marital ones, if he wants to. And if he doesn't want to, he doesn't.
Or perhaps you do not understand that people have a right to make vows, take them seriously, and expect that others will take them seriously.
Is there a Biblical injunction against the clergy being married? And the answer is no.
The RCC, due to tradition, has taken this and has made it a "rule" that clergy cannot be married.
Just one of many man-made rules by the RCC that contradicts the Bible.
Been good chatting with you.
