A coward's castle

(J. C. Philpot, "Inquiries and Answers")

A pastor has no right to turn the pulpit into a
coward's castle
, and from there attack those
in the congregation, whom he is afraid to meet
face to face privately.

It is cruelly unfair to attack an individual who
cannot defend himself—to hold him up, as if on
the horns of the pulpit, before the congregation,
(who generally know pretty well who is meant),
and to condemn him without hearing his side,
with the pastor being the only judge and jury.
