Trial and Companions
The surviving account of Philip's trial records a sequence of interrogations before successive governors. Bassus first demanded the church's sacred vessels and Scriptures; when the governor Justinus replaced him, he interrogated Philip without success and ordered him imprisoned. Philip was held for seven months with the priest Hermes and the deacon Severus before being transferred to Adrianople, where he was condemned to be burned alive.
A copy of the court proceedings against Philip is reported to have survived to the present day, making him one of the martyrs whose Acts rest on documentary record rather than later tradition alone. In the Western calendar his memorial is observed on October 22; in the Orthodox calendar he is commemorated on August 20.
