The point is continuity, not nostalgia. When Coptic is prayed in the Liturgy, the parish is praying with the memory of Egypt, the martyrs, the monasteries, and generations of faithful families who handed down the same worship.
Speaking to one another in psalms and hymns and spiritual songs.
The language of a received rite
Coptic is tied to the shape of the Coptic rite itself. Short responses such as Amen, Alleluia, Lord have mercy, and God have mercy on us are learned by repetition. Longer hymns preserve theological phrases, feast melodies, and ways of prayer that were carried orally for centuries.
That is why Coptic words can matter even when a parish also uses English or Arabic. The older language gives the worship a recognizable form, and the translations help the faithful understand what they are praying.
Understanding without losing memory
The best use of Coptic is intelligible inheritance. The Church preserves what was received and teaches its meaning through translation, preaching, classes, and repeated parish practice. English helps the words reach the people present now; Coptic keeps the parish connected to the Church that received and preserved those words.
This balance protects both memory and mission. A parish should make the prayers understandable while also honoring the language through which much of the Coptic Orthodox liturgical inheritance came to us.
