Note 407 — Chapter XIV

The title Patriarch is occasionally used in the following pages, although it does not appear to have been a formally recognised title till fifty years later. Socrates (A.D. 440 about) uses it (vide c. 8), but the first occurrence of it in any public document is in the acts of the Council of Chalcedon, A.D. 451, where it is applied especially to Leo i. of Rome.—Can. 28. Labbé, vol. iv.
