I've read here and there about the proper means of defending one's faith. It occurred to me at some time that the most useful, most effective, most reliable means of defending one's faith is to live it as it is meant to be lived, without stint, without quibble, without making a point of it.
It also occurred to me that this is by far the most difficult means of defending one's faith--one that, while not reserved to Saints, certainly most effectively demonstrated by them. Some of these Saints also defended their faith in other ways--in physical battle, in intellectual battle, in protracted debate. But others did not so engage, and yet they still won the hearts and minds and souls of a great many. I guess I would say that living your faith in its entirety is a precursor to being able to defend it in any intellectual capacity.
