Veneration

Up until the 17th century Clement was venerated as a saint in the Catholic Church. His name was to be found in the martyrologies, and his feast fell on the fourth of December, but when the Roman Martyrology was revised by Pope Clement VIII his name was dropped from the calendar on the advice of Cardinal Baronius. Benedict XIV maintained this decision of his predecessor on the grounds that Clement's life was little known, that he had never obtained public cultus in the Church, and that some of his doctrines were, if not erroneous, at least suspect.

Although Clement is not widely venerated in Eastern Christianity, the Prologue of Ohrid repeatedly refers to him as a saint, as do various Orthodox authorities including the Greek Metropolitan Kallinikos of Edessa.

The Coptic tradition considers Clement a saint. Saint Clement Coptic Orthodox Christian Academy in Nashville, Tennessee, is specifically named after him.

Clement is commemorated in Anglicanism.
