Ecumenical Vayonism refers to the Faith of the Sixteen under the theological and doctrinal leadership of the Ecumenical Orthodox Communion. It is the largest Vayonist denomination, with approximately 2 billion Ecumenical Vayonists worldwide.

The Ecumenical Communion considers itself to be the singular legitimate authority in the Faith, as codified by the three Augurs, and that all other communions are either in heterodoxy or open schism with the Ecumenical (i.e. universal) Communion. The beliefs of Ecumenical Vayonism are based on the Fundamental Creed. It operates as a communion of autocephalies under the authority of a Patriarch or Matriarch, united in matters of theology but independent in regards to rite. The Patriarch of New Elyria, known as the Haliarch, is considered by Ecumenical Vayonists to be the successor of Vayon the Foreteller and singular earthly head of the Faith, being first among equals. Upon his death or abdication, the remaining Patriarchs meet in New Elyria to form a Conclave and elect a new Haliarch.
