​CLETUS, formerly regarded as the name of one of the early successors of St Peter in the see of Rome, or, according to Epiphanius and Rufinus, as sharing the direction of the Roman Church with Linus during Peter’s lifetime. He has been identified beyond doubt with Anencletus (q.v.). See Père Colombier, in Rev. des questions hist. Ap. 1st, 1876, p. 413.
