The Nicene Age
Who Gregory the Illuminator was
The evangelizer of Armenia and founder of its national church — the first state in history to adopt Christianity. Of Parthian royal descent, reared a Christian in Cappadocia, he returned to Armenia, was tortured and (by the tradition) imprisoned thirteen years in a pit by king Tiridates III, then healed the king of a madness and converted him and the nation around 301, a decade before Constantine’s edict. Consecrated first Catholicos, he built the cathedral of Etchmiadzin at the site of a vision. His descendants held the Armenian primacy for generations. The father of the oldest national Christian church.
