Except that Rome has no chains. And you certainly don’t have to leave Christ Church - the Catholic Church - to be saved.
Actually, I have said that it is quite likely some within that monstrosity are being rescued. But, that is in spite of the errant teaching, not because of it. It is because they are among the elect and Jesus has sought them, even as Rome has attempted to brainwash them.
Leaving an organization which makes the ridiculous claims Rome has made is simply a good idea. Leaving would allow the escapee to receive better teaching, but not guarantee it. Only Christ can manage the destiny of a man. And, yes, remarks such as the following become chains:
Boniface VIII... "There is one holy Catholic and apostolic church, outside of which there is no salvation...it is altogether necessary for salvation for every creature to be subject to the Roman Pontiff." Unam Sanctum 1302AD.
Sounds cult-like to me.
