Patristic Quote of the Day

For even though the Spirit exist in His Own Person, and is conceived of by Himself, inasmuch as He is the Spirit and not the Son, yet is He not therefore alien from Him; for He is called the Spirit of truth [John 15:26], and Christ is the Truth [John 14:6], and He proceedeth from Him, just as from God the Father.— Third Letter of St. Cyril of Alexandria to Nestorius, read and accepted at the Council of Ephesus, 431.
