Commemorated on October 18

This Apostle was an Antiochean, a physician by trade, and a disciple and companion of Paul. He wrote his Gospel in Greek after Matthew and Mark, after which he wrote the Acts of the Apostles, and dedicated both works to Theophilus, who, according to some, was Governor of Achaia. He lived some eighty-six years and died in Achaia, perhaps in Patras, the capital of this district. His emblem is the calf, the third symbolic beast mentioned by Ezekiel (1:10), which is a symbol of Christ’s sacrificial and priestly office, as Saint Irenaeus says.
