He is venerated as a saint by the Roman Catholic and the Eastern Orthodox Church and his feast day is the 4 May and the 14 October, respectively.
[3] He then became known for his life of exemplary rectitude and piety and was therefore made presbyter of the Gazan church.
During the Diocletian Persecution he was condemned to work as a slave in the copper mines of Phaeno.
By that time he was already old and soon weakened under the atrocious work in the mines, making him incapable of continue to work though he encouraged his fellow Christians to remain strong in their faith.
When it was decided that those who were incapable of working in the mines were to be killed, Silvanus and 39 other Christians were martyred.
