Emergence of Oriental Orthodoxy in Guatemala was closely related to the process of canonical revival within particular Christian communities.
By 2012, first contacts were initiated between the Renewed Ecumenical Catholic Church of Guatemala (Iglesia Católica Ecuménica Renovada en Guatemala, ICERGUA) and representatives of Syriac Orthodox Church in North America, and within a year full communion was achieved.
[2] This revival movement was led by Eduardo Aguirre-Oestmann, a former priest of the Roman Catholic Archdiocese of Guatemala.
[3] In 2006, Cardinal Rodolfo Quezada Toruño, archbishop of the Archdiocese of Guatemala, excommunicated Aguirre and adherents of his group.
[4] They were excommunicated for schism, and Aguirre also for distancing himself "from the communion and the norms of his priesthood" by founding the Comunión Ecuménica Santa María del Nuevo Éxodo in 2003.
