He sent a letter exhorting the King of Armenia to accept the Council of Chalcedon and the councils that succeeded it; however, the Armenians steadfastly refused, while pointing out in there reply the similarity between Leo's Tome and the teachings of Nestorius, and the incoherence of the Chalcedonian Definition of Faith.
The Armenian letter does not prove that Leo and Chalcedon are guilty of Nestorian heresy simply because of some overlap. Theodotus overlapped with Nestorius when Thedotus referred to the visible nature and the God in the visible nature. Severus overlapped with Nestorius when he spoke of two hypostases united in Christ. The Armenian letter does not coherently explain how two natures remain unconfused if they are no longer two natures, but merely one nature. Is the united nature created or uncreated? Is the composite nature homoousios with the Father and Spirit or with humanity? Is the one nature passible or impassible? The Armenian letter seems to recognize the Orthodoxy and holiness of Saint Photius the Great, but it tries to defend the self-contradictory slogans inherited from the Greek Severians: "without confusion" and "no longer two, but one." Both slogans cannot be true.
