Christ: ‘the same perfect in divinity and perfect in humanity, the same truly God and truly man, of a rational soul and a body; consubstantial with the Father as regards his divinity, and the same consubstantial with us as regards his humanity …’ This still remains the standard measure for discussion of the person of Christ, in Churches otherwise as diverse as Greek, Romanian and Slavic Orthodox, Roman Catholics, Anglicans and mainstream Protestants. So, like Nicaea in 325, 451 remains an important moment in the consolidation of Christian doctrine into a single package for much of the Church.
