Note 374 — Chapter VII · PROBLEMS OF THE ARABIAN CULTURE (A) HISTORIC PSEUDOMORPHOSES
Charles Francis Atkinson translation
If the word “catholic” be used in its oldest sense (Ignatius ad Smyrn., 8)—namely, to signify the sum of the cult-communities, both the Churches were Catholic. In the East the word had no meaning. The Nestorian Church was no more a sum than was the Persian: it was a Magian unit.
