Genuine Orthodox Church of Greece (Old Calendar)
Schismatic Greek Orthodox jurisdictions that rejected the 1924 Greek Orthodox Church adoption of the Revised Julian Calendar. The largest body today is the 'Genuine Orthodox Church of Greece' under Archbishop Kallinikos (Synod of Kallinikos), with multiple smaller competing 'True Orthodox' synods (Lamia, Kiousis, Avlona).

Profile facts
In context
When the Church of Greece adopted the Revised Julian Calendar in 1924, a substantial minority of clergy and laity rejected the change as a Masonic / ecumenist innovation and broke communion. The resulting 'Old Calendarist' or 'True Orthodox Christian' (GOC, Genuine Orthodox Church) movement organised in 1935 around three bishops who consecrated successors. Multiple internal schisms have produced today's competing synods — the largest being the Synod of Archbishop Kallinikos II (in restored communion with the Russian Orthodox Church Outside Russia in some periods), plus smaller bodies including the Synod of Lamia (Maximos), the Kiousis Synod, and the Avlona Synod. Old-Calendarist communities maintain strict liturgical conservatism, oppose ecumenical contact with the official Church of Greece and the broader Orthodox communion, and treat the World Council of Churches as a heretical institution. The movement is large enough — perhaps 250,000–400,000 adherents in Greece plus diaspora — that it has its own monastic complexes (notably the Holy Monastery of the Transfiguration at Megara) and multiple seminaries. Member-control patterns are moderate (sharp inside/outside boundary, intense liturgical schedule, family-pressure on the 'New-Calendarist' relatives) rather than high — comparable to mainstream traditional Catholic SSPX, not to a destructive cult.
History
Schism dates to 1924–1935 over the Greek Church's adoption of the Revised Julian Calendar. Multiple competing synods exist today; the largest is the Synod of Kallinikos.
