The Ecumenical Synod of Qart Qildar was an Ecumenical Council of the Apostolic Church of the East that took place between 3977 and 3981, convoked in response to a number of challenges facing the Eastern Hosian Communion, particularly the ongoing Barmenian schism, Pneumatological controversies surrounding the issue of Eliyahu's humanity and divinity, and the need for a reorganization of the structure of the Church.
