Life and Martyrdom
By the account preserved in the synaxarion, Gelasius lived at a time of severe persecution of Christians. He distributed all of his property and possessions to the poor, clothed himself in a long white garment, and went out to visit those who were enduring martyrdom. He kissed the wounds of Christians who had been tortured in various ways and encouraged them to remain steadfast in their faith.
When the pagan authorities discovered his activity, he was seized and brought before a ruler for questioning. He proclaimed the divinity of Christ and denounced the idols as deaf and inanimate objects. The governor answered him with mockery and ordered him to be flogged, and afterward commanded that he be beheaded.
The sources record no place, date, or century for his life and death, and they preserve no further biographical detail.
