A bit off topic, perhaps, but to clarify. The word "church" is used in the Bible to translate "ekklesia" and (in the Book of Hebrews) "synagogue." "Ekklesia" is, roughly, an assembly and is used to describe gatherings of Believers and the mob that tried to kill Paul over a decline in Diana statues.If you don't believe in Jesus Christ why call your group a church. Why not a synagogue, temple, masque or what you really are a CULT.
When the King James was translated, the Puritans wanted "ekklesia" to be translated as "assembly" but, as the head of the Anglican Church, James vetoed the more accurate translation.
Except in the Book of Hebrews, it's never used to describe a building, in Paul's writings, "the church that meets in the house of ___" is used several times. Any gathering of people for any purpose is a church (technically).
As to "cult" in it's more accurate usage, it refers to any system of belief - all religions are cults - "cult" or "cultus" originally meant, simply, "worship." It is only in more common vernacular that "cult" has come to be used of religions considered spurious and basically just means, a religion not my own.
