Splash: this of course is NOT what is written in the latest secret Elders book, which says they CAN be reappointed.
Yes, known child abusers can be recommended as elders as long as the "sin" was years in the past:
"For example, the sin may involve past child abuse, and this would likely disqualify him for years." - Shepherd the Flock of God, p. 38 (2010)
Note that this potential "disqualification" is only "likely" and could only be "for years". Hmmm, Shepherding the flock takes on new meaning!
