The '''Church of the Genuine Orthodox Christians of Greece''' is an [[Old Calendarist]] body which in 1935 broke from the [[Church of Greece]] over the latter's use of the [[Revised Julian Calendar]]. The adoption of the new calendar was viewed as an assault on the ecclesiological beliefs of the Church, in that it allegedly which they believe promotes common worship with heretics to further non-Orthoox and furthers the goals of syncretistic [[Ecumenism]], while sacrificing liturgical unity among Orthodox Christians. It is not in communion with any of the [[List of autocephalous and autonomous churches|mainstream Orthodox churches]], though it has enjoyed occasional support from mainstream churches which have retained the [[Julian Calendar]]. It also has support from some of the monks of [[Mount Athos]]. Its current [[primate]] is Archbishop Chrysostomos II (Kiousis) of Athens and All Greece.
