I recently joined the Coptic Orthodox Church (was baptized, chrismated, and communed recently), and so am still learning a lot. I was wondering where we get a lot of our hymns from and how old a lot of them are? Specifically I have in mind songs like "Night of the Last Supper" or "The Burning Bush Seen by Moses." I was wondering this as I often see the lyrics to a lot of these hymns written in Arabic and English and not Coptic, leading me to think they were written after Coptic stopped being commonly used outside of the Liturgy.
P.s. forgive my ignorance on anything
