You raise an interesting point.
What I find interesting, perhaps intriguing is more accurate, is how the canon (Session 7 Canon 6) that BODers use to insist that Trent taught a BOD, in fact condemns the idea of a BOD as "justification through faith alone," which was the heresy Luther was preaching that they were condemning with anathema in that canon. I mean, it seems they never ask themselves, "exactly what is being condemned with anathema here?"
Further, how is it that the proponents of a BOD will not understand a BOD as the prot heresy of "salvation through faith alone" instead insist it is a doctrine of the Church? The standard answer here is numerous quotes from St. Thomas, St. Alphonsus and many others - just as if there is no contradiction whatsoever to Trent, or insisting there is no contradiction when plainly there is.
I understand how St. Thomas could be mistaken, but I do not understand how other theologians, great saints and doctors that are often quoted *after Trent* could have studied Trent and determined it taught a BOD rather than condemned the idea.
It's on the list of things that make me go hhmmm.
