Thanks for the Latin but I truly think that they know exactly what they are doing.
Well, they know what they’re doing when it comes to this thought process: “break/open tabernacle, take Host, turn around, run away, commit unspeakable sacrilege with said Host.” But they sure don’t seem to know the eternal consequences! Or, at the very least, they haven’t got a clue that they’re on the “wrong side,” and that the very Book inspired by the self-same Triune God they seek to violate in the Eucharist makes it clear that they will lose out in the end.
