The logos-theology of early Apologists identified Christ with the Greek term, logos, used for the notion of "Word" or "reason" in ancient Greek thought. In his divine character Christ was held to be identical with the logos of God. In his character as human, Christ was held to be identical with the man Jesus. The relation of the divine and the human would present a persistently difficult question for later theologians. The early church would attempt to resolve these questions most definitively in its ecumenical councils.
