Apparently it's now ok for known child abusers to 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!
