Like Basil the Great has said: 

"It is necessary to confess our sins to those to whom the dispensation of God’s mysteries is entrusted. Those doing penance of old are found to have done it before the saints. It is written in the Gospel that they confessed their sins to John the Baptist [Matt. 3:6], but in Acts [19:18] they confessed to the apostles" (Rules Briefly Treated 288 [ 374 A.D.]).
