Soter was of Greek origin, though born in Fondi, Italy. He reigned as Pope from 166-175. He was attentive to the needs of Christians and the east, and his pontificate was marked by works of charity and care for the poor. He fought against Montanism, and regulated the order of deaconesses.  

Prayer

O God, who to pasture your people filled the Bishops, blessed Soter with a spirit of truth and of love, grant that, as we celebrate his feast day with honor, we may benefit by imitating him and be given relief through his intercession. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever. Amen.

St. Soter prayer for us.
