And I believe the Catholic position is that the price of divorce here on earth is that you aren't allowed to remarry. That doesn't mean you you can't be forgiven and still have salvation. Like I said, I am not a Catholic and am not saying I necessarily agree with their position but I do understand their reasoning and position.
I believe you are right about their position. And they have the right to hold that position with regard to their members. Just makes me glad I am not a Catholic! :-)
That is not a price or penalty for divorce. Following the clear teaching of our Lord, divorce is not possible. Since the so-called "divorced" marriage is still an active and continuing marriage, sexual relations in violation of it are adultery.
