Russian philosophical theologian. He was one of the founders of the Slavophile movement which he tried to build up on Orthodox Christianity. Over against the RC (‘unity without freedom’) and the Protestant (‘freedom without unity’) conceptions of the Church, Khomiakov saw in the Orthodox Church an organic society of which Christ was the Head and the Holy Spirit the Soul and whose essence was ‘freedom in the spirit at one with itself’. Of this Church the essential quality was inward holiness, and those who partook of it could be saved even though not in external communion with it. Khomiakov's conception of the Church (often summed up in the term ‘sobornost’) has influenced Orthodox ecclesiology, Greek as well as Russian.
