Titus Flavius Clemens (c. 150 - c. 215), kwn as Clement of Alexandria to distinguish him from the earlier Clement of Rome, was a Christian theologian who taught at the Catechetical School of Alexandria. A convert to Christianity, he was an educated man who was familiar with classical Greek philosophy and literature. As his three major works demonstrate, Clement was influenced by Hellenistic philosophy to a greater extent than any other Christian thinker of his time, and in particular by Plato and the Stoics. His secret works, which exist only in fragments, suggest that he was also familiar with pre-Christian Jewish esotericism and Gsticism. In one of his works he argued that Greek philosophy had its origin among n-Greeks, claiming that both Plato and Pythagoras were taught by Egyptian scholars. Among his pupils were Origen and Alexander of Jerusalem. Clement is regarded as a Church Father, like Origen. He is venerated as a saint in Oriental Orthodoxy, Eastern Catholicism and Anglicanism. He was previously revered in the Roman Catholic Church, but his name was removed from the Roman Martyrology in 1586 by Pope Sixtus V on the advice of Baronius.
