St Mamas was from Gangra of Paphlagonia. He was born in prison, where his parents Theodotus and Rufina were suffering for Christ's sake and where they ended their lives. He was named Mamas because, after he had long remained without speaking, he addressed his foster mother Ammia as "mama". Ammia died when Mama was 15 years old.
St Mama was tortured for his Christian faith by orders from the governor of Caesarea and was then sent before Emperor Aurelian who had him tortured again. He was later thrown to the lions, but they remained docile, and a lion remained with him as his companion. He contested for Christ about the year 275 AD.
Dismissal Hymn (Fourth Tone)
Your Martyr, O Lord, in his courageous contest for You received as the prize the crowns of incorruption and life from You, our immortal God. For since he possessed Your strength, he cast down the tyrants and completely destroyed the demon's strengthless presumption. O Christ God, by his prayers, save our soul, since You are merciful.
Kontakion (Third Tone)
With the staff bestowed on you by God, O holy Great Martyr, shepherd us your people in green and life-giving pastures; swiftly crush with godly power unseen and wild beasts underneath the feet of them that praise you with longing; for in dangers we all have you, O Mamas, as our fervent protector and help.
