Pantaenus was a Stoic philosopher teaching in Alexandria. He was a native of Sicily. He converted to the Christian faith, and sought to reconcile his new faith with Greek philosophy. His most famous student, Clement, who was his successor as head of the Catechetical School, described Pantaenus as "the Sicilian bee". Although no writings by Pantaenus are extant, his legacy is known by the influence of the Catechetical School on the development of Christian theology, in particular in the early debates on the interpretation of the Bible, the Trinity, and Christology. He was the main supporter of Serapion of Antioch for acting against the influence of Gnosticism. map showing ancient trade routes In addition to his work as a teacher, Eusebius of Caesarea reports that Pantaenus was for a time a missionary, traveling as far as India where, according to Eusebius, he found Christian communities using the Gospel of Matthew written in "Hebrew letters", supposedly left them by the ApostleBartholomew. This may indicate that Syrian Christians, using a Syriac version of the New Testament, had already evangelized parts of India by the late 2nd century. However, some writers have suggested that having difficulty with the language of Saint Thomas Christians, Pantaenus misinterpreted their reference to Mar Thoma, who is currently credited with bringing Christianity to India in the 1st century by the Syrian Churches, as Bar Tolmai. The ancient seaport Muziris on the Malabar Coast was frequented by the Egyptians in the early centuries AD. Saint Jerome, apparently relying entirely on Eusebius' evidence from Historia Ecclesiastica, wrote that Pantaenus visited India, “to preach Christ to the Brahmans and philosophers there.” It is unlikely that Jerome has any information about Pantaenus' mission to India that is independent of Eusebius. On the other hand, his claim that "many" of Pantaenus' Biblical commentaries were still extant is probably based on Jerome's own knowledge. His feast day is July 7.
The Universalist Church of America historian J. W. Hanson argued that Pantaenus "must, beyond question" have taught Universalism to Clement of Alexandria and Origen. However, since it is now considered that Clement of Alexandria's views contained a tension between salvation and freewill, and that he and Origen did not clearly teach universal reconciliation of all immortal souls in their understanding of apokatastasis, Hanson's conclusion about Pantaenus lacks a firm basis.
