Perfecti were the inner circle of initiates in the medieval religious sect of the Cathars.

Perfecti vowed to live in absolute celibacy, not to eat meat, to fast on several days each week, and to pray a certain number of paternosters each day. By that virtue they were recognized as trans-material angels by their followers, the conversi. Though there is a Cathar church in America today, the last Perfectus died in the 14th century, effectively ending the disciplic succession of perfecti.
