Consequently, our acceptance
of supernatural faith (by grace alone) is in harmony with modern historical reasoning and philosophical reflection on the ordinary human transmission of knowledge.
Second, the act
of supernatural faith is a grace that allows us to accept divine testimony with an unfailing certitude, by an act of the will moved by charity, the love for God poured into our hearts by the Holy Spirit.
For Augustine, the grace of
supernatural faith is much like this balanced, natural form of trust, but it differs in two key respects.
Supernatural faith is stronger, therefore, than any human trust, even trust that one has in a parent or a spouse.
The implication of the difference between supernatural belief and natural belief was that the Christian, through the acceptance of a supernatural revelation by an act of
supernatural faith and through baptism, was incorporated into a sacred society called the Church which had a sacred history.
