In this opening volume to his Formation of Christian Theology series, John Behr looks at the implications formed out of Jesus' question of 'Who do you say I am,' and journeys into the formation of the earliest churches who truly believed him to be the Christ. From here Behr makes an accounting of Christendom's most vehement defenders concerning Christ's lordship, from Ignatius of Antioch through Justin Martyr and Irenaeus, to Paul of Samosata and the Council of Antioch. Ultimately, Behr offers discussion and commentary on the formation of Orthodox theology, through the eyes of its earliest founders.
