“A church which no longer takes the rejection of false teaching seriously no
longer takes truth, i.e. its salvation, seriously, and ultimately no longer takes the
community seriously, no matter how pious or well-organised [sic] it may be.
Anyone who follows false teaching, indeed who simply supports and furthers
it, no longer obeys Christ.”
Dietrich Bonhoeffer
