Soter was the twelfth bishop of Rome, serving from approximately 167 until his death around 174 or 175. Born into a Greek family in Fondi, he was deeply connected to his heritage, which influenced his interactions with the Church in Corinth. During his leadership, he established the annual celebration of Easter in Rome and mandated that marriage be recognized as a sacrament requiring a priest's blessing. He is recognized as a saint in the Catholic, Orthodox, and Anglican traditions.
