Well let's take one thing at a time. I'm happy to debate the point directly from Trent, so long as I'm also on record noting that the real problem here is a fundamental misunderstanding of Catholic learning viz. disregard for the ordinary magisterium.
When describing the justification of the sinner before baptism, Trent teaches (contra the Protestants) the initiatory role that faith plays in that process. It says faith comes from hearing, not baptism. Denz 798
"Now they are disposed to that justice [can. 7 and 9] when, aroused and assisted by divine grace, receiving faith "by hearing" [Rom. 10:17], they are freely moved toward God, believing that to be true which has been divinely revealed and promised..."
.
It says the virtues are infused at baptism too, of course, which only makes sense given the (again, contra Protestants) *continued* justification of souls.
