Also known as Anencletus and Cletus, St. Anacletus was the third Pope. His Papacy lasted twelve years between 76 and 89. It is believed he was martyred c.89 by the Roman Emperor Domitian and buried near St Peter and St Linus, his two predecessors, in the Vatican. Very little is know about him and his most spoken about due to the debate other whether Cletus and Anacletus were one person or different Popes. Karen Rae Keck points out,
"Because the name Anacletus (or Anencletus), which means blameless, was common among Greek slaves, some scholars doubt that Anacletus existed"
However scholars seem to have dismissed this possibility,
"All other ancient papal lists, from the second to the fourth century, give as follows the immediate succession of St. Peter: Linos, Anegkletos, Klemes (Linus, Anencletus, Clemens), and this succession is certainly the right one" - JP Kirsch (Catholic Encyclopaedia)
with an explanation coming from John Chapman (Catholic Encyclopaedia), "Anacletus is a
Latin error; Cletus is a shortened (and more
Christian) form of Anencletus".
Anacletus was Greek and he is thought to have been a respected companion of the disciples who was converted by St Peter himself. He is known to have ordained around twenty five priests and assigned them to twenty five parishes which he divided Rome into. The belief that he was martyred seems to be largely based on his inclusion in the Roman Canon of the Mass as a martyr. Similarly there is no date for his canonisation although his saint day is 26 April.
