Why do we trust the Bible? And more specifically, why do we trust the Catholic Bible?
Frequently, morality is spoken of as something akin to the offside rule in soccer: an arbitrary rule imposed by a higher authority that keeps up from getting to do what would make us happy. But this gets morality wrong in every way.
Just as the Bible presents Abraham as our father in faith for his radical willingness to trust God, we're also given a mother in faith: the Virgin Mary. Listen to what Scripture says about her role in following God from the Annunciation to Calvary and into glory.
Why is Abraham our father in faith? Because of his primacy and because of his intensity - an intensity we see most clearly in the shocking account of the Sacrifice of Isaac.
