Sean, stop derailing this thread.
This thread is about the question of whether people who don't believe explicitly in Jesus Christ and the Holy Trinity can have supernatural faith.
While it has implications for BoD, these are not to be conflated.
Depending on the answer to this question, all that's at issue is the extent of BoD, whether it can apply to any infidel who believes in God or only to those who believe in Jesus Christ and the Holy Trinity. That's what Last Trad is pointing out.
You beg the question by assuming there's an implicit BoD and then conflate it with implicit faith. St. Alphonsus, for instance, believed in an implicit BoD, but not an implicit faith (i.e. believed that explicit faith was required for implicit BoD). That example alone suffices to expose your conflation of the issues.
Very few concepts, if any, have done more damage to theology, and opened the door to Modernism, than this notion of implicit.
Explicit BoD: I am a catechumen who believes in all that the Church teaches, and I want to become a Catholic, and I desire to receive the Sacrament of Baptism.
Implicit BoD 1: I am a catechumen who believes in all that the Church teaches, and I want to become a Catholic. I don't explicitly think, "I wish to receive the Sacrament of Baptism." Here the desire for Baptism is implicit in wanting to become a Catholic (since Baptism is the way to do it).
Implicit BoD 2: I believe in Jesus Christ and the Holy Trinity, and I desire to do whatever they ask of me. I don't know about the Catholic Church. Here there's an implicit desire to become Catholic, and therefore an implicit desire to be baptized. This is one step removed from the one above.
Implicit BoD 3: I am a Jew or Muslim who believes in God, or even some animist in the jungles of Africa, and I desire to do whatever God wants. So that means I implicitly desire to convert and believe in Jesus and the Holy Trinity. So this is exactly one more step removed from the one above.
Implications of this issue are only for scenario #3 above. St. Thomas,, St. Thomas, and -- according to Msgr. Fenton -- the majority of theologians (even in his day) reject scenario #3, stating that one cannot have supernatural faith without a bare minimum of explicit faith in the Holy Trinity and Incarnation.
