It contains such nice quotes as:
"Before forming a committee, elders determine if the accu-
sation has substance.
It must Scripturally be an offense serious enough to
result in disfellowshipping.
There must be either two witnesses or a confession of
wrongdoing.
If there is not enough evidence to form a committee
but serious questions have been raised, two elders may
be assigned to investigate the matter. "
"Instead of looking for rigid rules for guidance, elders
should think in terms of principles; judge each case on its
own merits. "
"There must be two or three eyewitnesses, not just persons
repeating what they have heard; no action can be taken if
there is only one witness. (Deut. 19:15;Jol1ll 8:17)
Confession (admission of wrongdoing), either written or
oral, may be accepted as conclusive proof without other
corroborating evidence. (Josh. 7:19)
Strong circumstantial evidence, such as pregnancy or evi-
dence (testified to by at least two witnesses) that the
accused stayed all night in the same house with a person of
the opposite sex (or in the same house with a known
homosexual ) under improper circumstances, is acceptable."
" In cases where it is established that a serious sin was
actually committed, the judicial committee should con-
sider such factors as these:...Are there extenuating factors, such as emotional or
mental disorders or having been a victim of some type
of abuse in the past, that should be considered?
Was it a single offense, or was it committed more than
once? ...Was his confession voluntary, or did he have to be ac-
cused by others before confessing?
Was his reluctance to speak more a result of deep shame
than of lack of repentance?
Above all does he show true repentance and manifest a
heartfelt desire to avoid repetition of the wrong?
Even though the wrongdoer is guilty of a serious of-
fense, elders on the judicial committee realize that their
aim is to recover the one who has fallen into a wrong
course, whenever this is possible. (Jude 23 )
