[quote=davidc2]I haven’t seen anyone kiss an abbot’s ring - but I don’t know if that is traditional or not.
The easiest way to address an abbot is “Fr. Abbot”.
Not much you can do to tell the difference between a brother and a priest monk (except when they are vested for Mass).
About all you can do is call them all one or the other - and they’ll correct you when appropriate.
The abbot’s jurisdiction, if he is a “mitered Abbot” is only for his community. I doubt anybody today would expect you to kiss a ring – IF he wears one.
How about saying: “Brother – or is it Father?”
