Early Christian Prayer Hall
Megiddo Church (Christian Prayer Hall)
meh-GID-oh CHURCH · Modern Megiddo Prison, near Tel Megiddo, Israel · Also called Megiddo Church · 32.5712° N, 35.1913° E
In 2005, prisoners doing salvage excavation ahead of a Megiddo Prison expansion (at ancient Kfar Othnay/Legio) uncovered the floor of one of the world's oldest known Christian prayer halls, commonly dated to roughly AD 230 on the basis of pottery, coins, and the style of its inscriptions — though some scholars argue for a later conversion in the late third or early fourth century. If the earlier date holds, it is the earliest identified Christian prayer hall yet excavated, predating the Dura-Europos house church (converted c. AD 240/241); it differs from Dura in being a room within a larger secular building associated with the Roman legionary settlement rather than a building dedicated wholly to Christian worship. A mosaic bears a Greek inscription stating that "the God-loving Akeptous has offered the table to God Jesus Christ as a memorial" — one of the earliest surviving inscriptions to explicitly call Jesus "God," predating Constantine's legalization of Christianity by nearly a century.
Archaeology
Excavated in 2005 by Yotam Tepper (Tel Aviv University/Israel Antiquities Authority). The c. 230 AD date rests on associated pottery, coins, and lettering style; the room appears deliberately covered around 305 AD, plausibly to hide it during the Diocletianic persecution. Some scholars argue the structure may be a later conversion of an earlier building rather than purpose-built — the early date is well-supported but not universally uncontested.
