Hmmm.. Now that you mention it, no, I did not. Perhaps there is no satisfactory answer?
Considering what we have seen just this week from RCs, then "satisfactory" or whatever can mean whatever they see it as, but there is indeed no proof for this fallacious assertion, or for the others. Thus silence or the recourse to ad hominems and accusing the one of lying who exposed the lying. And the week is hardly half over!
But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. (Ephesians 5:13)
