Paul, in Titus i, 14, says: "Teach them not to give heed Titus to
Jewish fables, and commandments of men, that turn them from the
truth." [Titus 1:14]
[Sidenote: Christ, or Men?]
This is a strong command, that we are not at all to regard the
commandments of men. Is not this clear enough? And Paul gives his
reason: they turn men from the truth, he says. For as has been said
above, the heart cannot trust in Christ and at the same time in the
doctrines or the works of men. Therefore, as soon as a man turns to
the doctrines of men he turns away from the truth, and does not regard
it. On the other hand, he who finds his comfort in Christ cannot
regard the commandments and the works of men. Look now, whose ban you
should fear most! The pope and his followers cast you far beyond hell
if you do not heed their commandments, and Christ commands you not to
heed them on pain of His ban. Consider whom you wish to obey.
