Revised Julian calendar
In 1998, plagued by moral and financial scandals, two bishops who had broken off from the Church of the Genuine Orthodox Christians in the United States were re-baptized and re-ordained by the Ecumenical Patriarchate and put under the leadership of the Greek Orthodox Church in the U.S. (which uses the Revised Julian calendar). In exchange, the few priests that went with them were accepted as Orthodox priests, and their churches were allowed to maintain their use of the Julian calendar. Later these parishes were forced to switch to the Revised Julian calendar although allowed to remain using their more traditional liturgy.
