Certainly, criticism of the reverend clergy must be done w/the respect that their ordination and office call for, but I do not see anything wrong with respectfully criticising the clergy when we disagree with them, sometimes, when their actions may render them more like layman than clergy.
I've openly disagreed with the GOAA's Eparchial Synod, in instances such as the Constitutional Charter they pushed on us, at the behest of the Patriarchate. I also recall former Archbishop of America Spyridon, staring me down when I tried to introduce a motion to elevate the diocesan structure at the time, to the full canonical authority of a diocese, at the Orlando Clergy-Laity Congress. And, I sincerely believe the information published by Orthodox Christians for Accountability was inspired work, that has returned the OCA's Central Administration to a proper course for the national church to be pursuing, rather than the fallen path it had been pursuing for way too many years. Again, "speak the truth in love," as the patron saint of my parish wrote.
