ekklēsía(from 1537 /ek, "out from and to" and 2564 /kaléō, "to call") – properly, people called out from the world and to God, the outcome being the Church (the mystical body of Christ) – i.e. the universal (total) body of believers whom God calls out from the world and into His eternal kingdom.[The English word "church" comes from the Greek word kyriakos, "belonging to the Lord" (kyrios). 1577 /ekklēsía ("church") is the root of the terms "ecclesiology" and "ecclesiastical."]
