My question is what are the original rites concerning this hymn? I'm not referring to the rite that we hear all the old amos in church say, which is "only if pope is here."
The kholagy that the Dioceses of Los Angeles, Hawaii, and the Southern United States use states (word for word):
"If the Pauline Epistle is read in Coptic, the following introduction is chanted:
Pavlos evok empenchoise....(continuation of the Coptic introduction)"
Then it goes on to say the following:
"After the reading, the following conclusion is chanted:
Piehmot ghar je amen eseshopi
Piehmot ghar... (continuation of the hymn)"
I'm thinking that since it doesn't say something along the lines of "If the Pope, Metropolitan(s), or Bishops(s), is (are) attending, then the following is chanted" like it says for "Ni savev teero" or "Marochasf," then this hymn can be said on two occassions:
1. After the Coptic Pauline Epistle or the Intercessions if the Pope, Metropolitan(s), or Bishops(s), is (are) attending.
2. After the Coptic Pauline Epistle and skip the part about the bishop.
I say "skip the part about the bishop" because in the kholagy, it says "In the presence of a metropolitan(s), bishop(s), the following is said:
Nem peniot.... (continuation of the hymn).
which means that pi-ehmot ghar is said only after the Pauline Epistle in Coptic.
The second source is the common (most likely misinterpreted) one that it is said only in the presence of the pope, metropolitan(s), bishop(s).
