One of the purposes of writing anything down is so that it’s the same for everybody. That’s why God caused His word to be written down.
St. Peter warns us against “private interpretation” of the scriptures. It would be hard to think of a warning that’s been less heeded.
And anyway, look how hard it is to convince anybody of anything. How often does anything we say actually change anybody’s mind?
Well, we try. “Don’t say I didn’t warn you” is a motto for this age.
