To Babai, Christ is both God and man. But he could not tolerate any form of Theopaschism (the belief that God suffered), be it the divinity itself, the Trinity, or one of the hypostases of the Trinity. According to Babai, Cyril of Alexandria stood at the root of simple Theopaschism as professed by the Miaphysites, and the Emperor Justinian I at the root of composite Theopaschism. The Church of the East could accept expressions like 'Christ died', 'the Son died', but not 'the Word died', even not 'the Word died in the flesh'.
