In his various roles, as missionary theologian, Apologist, and polemicist, Clement developed or touched upon ideas that were to influence the Christian world in the areas of monasticism, political and economic thought, and theology. In this last area, the Greek church regarded his views as too close to Origen’s, some of which were considered heretical. In the Latin church, however, he was regarded as a saint, and his feast day was celebrated on December 4. In 1586, however, because some of his views were questioned in regard to their orthodoxy, Pope Sixtus V deleted his name from the Roman martyrology.
