Feast of St. Thomas Aquinas
The atheist denies the very Source of all goodness in the first place - this is the beginning of hypocrisy: deliberate contradiction between his perverted conviction and his shots at philanthropy (a good our fallen nature is still capable of even deprived of charity, cf., Rom. XIII.3) which his fellow "stultus" in Papal trappings extols. Not necessarily and always the case with his 'hypocritical Catholic" - contradiction is most often than not as not by conviction as by weakness: easily a prey to human respect, passions, or vicious customs.
Better a 'hypocritical' Catholic in his calculation than a deliberate Antipope (for the devil had well forseen his fate and yet still: so be it! - the real "stultus": Latin of "stupid") - the true-blooded hypocritical 'Catholic'.
