Saint Phoebe the Deaconess is mentioned by the holy Apostle Paul (Romans 16:1-2).
Troparion — Tone 3
Enlightened by grace / And taught the Faith by the chosen vessel of Christ, / You were found worthy of the diaconate; / And you carried Paul’s words to Rome. / O Deaconess Phoebe, pray to Christ God that his Spirit may enlighten our souls!
