“Church” is not derivative of “Circe.” It is derivative of the Old English word “cirice,” which, as Merriam-Webster points out, is ultimately derived from the Greek [i]kyriakon[/i], the neuter form of [i]kyriakos[/i], “of the Lord.” Note that the ‘lord’ here referred to is not ‘Baal’ as several search engine hits on “circe daughter of baal” say, but is instead the same word that is used for the Lord Jesus himself, and for God the Father, the Lord.
