I’m off on vacation for the next two weeks but I will just say your posts are simply proof Catholics believe 1) a person can lose their salvation, and 2) a person must do works to maintain their salvation. Both are in error and are not according to the traditions laid down by the early church fathers. They are semi-Pelagius in their teachings which is heresy and was condemned by the Church-at least what used to be the Church. They will not save you.
This is where “free will” leads you.
