As for Trent, it is teaching that BOTH are needed. "CANNOT WITHOUT" refers to a necessary cause but not a sufficient cause. Trent is teaching that one cannot be justified without both the Sacrament and the desire to receive it. Trent's main teaching is that the Sacraments work based on a combination of completely free grace working ex opere operato along with cooperation of the will. There's actually a Canon which condemns the proposition that the Sacraments work magically even without the will to receive them.
Trent says you can't be justified without the laver of redemption OR the desire thereof.
Or in other words: You can't have C without A or B.
And you're apparently saying this means you need BOTH A and B to have C?
Let's see if that makes sense....
You can't get groceries without cash or credit.
You can't go to the store without transportation, or walking.
No, that doesn't mean both are needed. In those examples, either A or B gets you C.
But you may object that in the above examples, the
reality is that either one works.
What if we tried to write the same line about somehting that really does require both?
You can't work in the US without ID or employment eligibility.
Does that say you need both ID AND employment eligibility? No, it doesn't. It looks to me just like the other 2 examples. Grammatically, it says either one or the other is needed. On the other hand:
You can't work in the US without ID and employment eligibility.
Now, THAT would say in a clear manner. that both are needed.
Also, if both the sacrament AND desire were required, wouldn't that exclude children?
So it looks to me like you are misinterpreting Trent.
We have a bunch of Trad-Prots here who like to yank one statement completely out of context and misrepresent it as teaching doctrine ... just like Prots do with Scripture. Hey, it says "call no man father," see? You do the same thing, except the only difference is that you acknowledge two sources of revelation, and they only one.
There may be some Roman Protestants around, but perhaps they're not who you were thinking of, Laddy.
