Hierotheus, the first Bishop of Athens, was converted to Christianity by the Apostle Paul along with Saint Dionysius the Areopagite. He was consecrated to the rank of bishop by Paul and died a martyr in the first century. According to tradition, he was present at the funeral of the Theotokos.
Some believe that Hierotheus and Dionysius were members of the court of Mars Hill and that Hierotheus became Bishop of Athens after being instructed in the faith by Paul. He played a key role in teaching Dionysius about the mysteries of Christ.
Hierotheus was also present at the Dormition of the Theotokos, where his divine chanting inspired worship in many. He was known for his deep communion with sacred hymnology and lived a life pleasing to God before his martyrdom.
As a companion of Saint Dionysius, Hierotheus received the Christian faith from Paul and later became the bishop of Athens. He participated in the burial of the Theotokos and converted many pagans to Christianity through his evangelism. He was revered as a hierarch and a martyr in the Heavenly Kingdom.
