Ecclesia - the Church

Our Lord and the New Testament writers neither coined this word nor employed it in any unusual sense. Before their time it was in common use, of well understood signification, and subject like any other word to varied employment, according to the established laws of language. That is, it might be used abstractly, or generically, or particularly, or prospectively, without losing its essential meaning. To simplify and shorten the work before us, we need not leave the New Testament to find examples of its classic or Septuagint use. Fair examples of both are in the list of New Testament passages given you.
