Yes, there is a grave difference, one which has caused much heart-ache to the Russian Orthodox...
Some Antiochian Orthodox priests have been known to... I almost can't bear to relate this (shudder)... shave their beards.
The Russian Orthodox, who know in their hearts that a beard is approaching proper length when one can use it to dust the church floor when kneeling in worship, pray without ceasing that their Antiochan brethren will repent of this scandal and return to the true path.
It greives me to mention this matter, but the truth must be told.
You can see here that he is making much progress in growing it anew.
