@frawley -I do know, that until recently, it was considered bad etiquette or bad style for a Catholic bishop (at least in the USA) to wear a mustache or beard. In the 1890's it was actually I think prohibited, because many USA bishops thought that priests and/or bishops wearing beards or mustaches was too much like Protestant clergy, which many of them wore beards or mustaches or untrimmed sideburns. Under our Archdiocese of Philadelphia's last great CArdinal Archbishop, John Krol (1961-1989 term), it was prohibited for priests and seminarians to wear beards or mustaches. John XXIII was very much against beards or moustaches for the clergy in general, but he made exceptions for Eastern Rite clergy and 2-3 Cardinals who had adopted the habit.
