Divine Liturgy of St. John Chrysostom
The Second Vatican Council urged the Eastern Rite Churches to eliminate liturgical Latinization and to strengthen their Eastern Christian identity. In June 1999 the Council of Hierarchs of the Byzantine Metropolitan Church Sui Iuris of Pittsburgh U.S.A. promulgated the norms of particular law to govern itself. In January 2007, the Revised Divine Liturgy of St. John Chrysostom and the Revised Divine Liturgy of St. Basil the Great were promulgated. In December 2013, the Pope approved the request of the Congregation for the Eastern Churches that appropriate Eastern Church authorities be granted the faculty to allow pastoral service of Eastern married clergy also outside the traditional Eastern territory.
