Saints Agapius, Theognis, and Pistus were the sons of Saint Bassa, and lived in the city of Macedonian Edessa. From childhood they had been raised in the Christian Faith, but their pagan father denounced his wife and chldren to the governor. In spite of threats, they all refused to offer sacrifice to idols.
The skin of the young Agapius was flayed from head to chest, but the martyr did not utter a sound.
One account says that the three brothers suffered at Edessa in Macedonia. Another account says they died at Larissa in Thessaly, their homeland.
