ecclesiastical: [15] In classical Greek, an ekklēsíā was an ‘assembly’ (the word was derived from ekkalein, a compound verb formed from the prefix ek- ‘out’ and kallein ‘call’). With the introduction of Christianity, it was adopted as the term for ‘church’, and an ekklēsiastés, originally ‘someone who addressed an assembly’, became a ‘preacher’ or ‘priest’. The derived adjective, ekklēsiastikos, passed into English via either French or Latin.
