Clement of Alexandria, born Titus Flavius Clemens around 150 AD, was a Christian theologian and philosopher who taught at the Catechetical School of Alexandria. He is regarded as a Church Father and is considered the most influential Christian thinker of his time in synthesizing Hellenistic philosophy, particularly Plato and the Stoics, with Christian theology.
Clement's three major surviving works form a trilogy: the Protrepticus, written around 195 AD; the Paedagogus, written around 198 AD; and the Stromata, written from around 198 AD to around 203 AD. He also wrote the treatise Salvation for the Rich around 203 AD, and other works survive only in fragments.
Clement's name was removed from the Roman Martyrology on the advice of Cardinal Baronius when Pope Clement VIII revised the martyrology. Pope Benedict XIV maintained this decision because Clement's life was little known, he had never obtained public cultus in the Church, and some of his doctrines were considered at least suspect.
Clement argued that Greek philosophy served a preparatory role for the Greek world, similar to the function of the law for the Jews. He defined philosophy as "the desire for true being and the studies which lead to it," and held that true philosophy and authentic human knowledge originate in the Logos, which is the unique source of all truth.
Clement is regarded as one of the first Christian universalists. He espoused a belief in the eventual salvation of all, holding that divine punishment is corrective and remedial rather than purely retributive. In Stromateis 7:2:12 he states that God's project is universal salvation.
Clement's pupils at the Catechetical School of Alexandria included Origen and Alexander of Jerusalem. Alexander of Jerusalem later described Clement as "the holy Clement, who was both my master and benefactor," and praised him among "the blessed fathers who have trod the path before us."
