Saint Baptus was a soldier who suffered martyrdom with Sts Charalampus, Bishop of Magnesia, Porphyrius, and three women in the year 202.
Seeing the endurance of StCharalampus and his complete lack of malice, two soldiers (Porphyrius and Baptus) openly confessed Christ, for which they were immediately beheaded with a sword.
Troparion - Tone 4
Your holy martyr Baptus, O Lord,
Through his sufferings has received an incorruptible crown from You, our God.
For having Your strength, he laid low his adversaries,
And shattered the powerless boldness of demons.
Through his intercessions, save our souls! SOURCE:
