A thoroughly revised and expanded edition of this classic work to complete John McIntyre's trilogy in Christian doctrine: soteriology, pneumatology and Christology.McIntyre analyses the three classic christological formulations: the two-nature model with divine and human natures uniting in Jesus Christ; the psychological model, derived from the chalcedonian understanding of the humanity of Christ, and from a strong devotional desire to know his mind; and the revelation model, which has dominated western Christology for most of the twentieth-century.
