Saint Evangelicus, a follower of the holy Apostle Andrew (November 30), is the first known bishop of the diocese of Tomis (Constantsa) in Dacia Pontica (Lesser Scythia, or Dobrogea). He was active around the mouths of the Danube toward the end of the third century.
Bishop Evangelicus converted many pagans of Dacia Pontica to Christianity. He is mentioned in the account of the martyrdom of Sts Epictetus and Astion (July 8), where he is described as the founder of churches in the province. The parents of these holy martyrs were baptized by St Evangelicus after being converted by the priest Bonosus.
It is believed that St Evangelicus suffered martyrdom during the persecution of Diocletian (284-305).
