Quadratus of Athens, or Saint Quadratus of Athens, was a pastor in the early church, supposedly in Athens, Greece. He is mentioned in the writings of church historians Eusebius and Jerome. Most of the writings of Quadratus of Athens are lost today, but we do know he wrote an apologetic argument for Christ’s deity to the Roman Emperor Hadrian, c. AD 124. Eusebius records that Quadratus of Athens was a disciple of the original apostles and that, after Publius, leader of the church at Athens, was martyred, Quadratus took his place and brought spiritual comfort to the Christians there. Both the Roman Catholic Church and the Eastern Orthodox Church have canonized Quadratus of Athens. The Eastern Church also considers him one of the seventy (or seventy-two) disciples mentioned in Luke 10:1.
