"It is necessary to confess our sins to those whom the dispensation of God's mysteries is entrusted." Basil, Rule Briefly Treated, 288 (A.D. 374).
Basil is, of course, referring to the act of Christ whereby he endowed the Apostolic ministry with the office of remitting sins:
"If you forgive the sins of any, they are forgiven. If you retain the sins of any, they are retained" (Jn 20:23).
