Finally in 451, at the Council of Chalcedon, Pulcheria enforced a compromise: in the Union of Two Natures, Jesus was ‘perfect in divinity, and perfect in humanity’. Eudocia agreed and became reconciled with Pulcheria. This compromise has lasted to this day in the Orthodox, Catholic and Protestant Churches, but it was flawed: the Monophysites and Nestorians, for precisely opposite reasons, rejected it and split off from Orthodoxy for ever.
