Offering a perspective as an ethnic Copt, it is notable that most of the charms, “spells”, whatever you would call them, shown here, would be considered heretical today by Copts, though with the exception of basic crosses and icons and inscriptions limited to that of protection. The love spells and and such are in many a cautionary tale told to kids growing up to avoid at risk of invoking evil, so to say. Most of those stories come from the period where the “old religion” and Christianity were in flux.
Copts do also maintain a significant amount of syncretism with ancient Egyptian religion as well, both within language (typically, Egyptian Arabic words that are “odd” to middle eastern speakers are pulled from Coptic or earlier stages of Egyptian), and within ceremony (musical scales that do not sound “middle eastern” and are derivations of older Egyptian ceremony), and a belief that the Ankh, Hathor and Horus, etc. were precursors to modern Coptic religion.
