While I absolutely agree with brother Didymus and others, I would still say that there is a difference between Holy Confession (a Sacrament or a Holy Mystery of the Church) and spiritual conversation. If you are not yet baptized and chrismated Orthodox, your eye-to-eye conversations with your priest and your admittance of your sins is still NOT a Holy Confession. UNTIL you are fully received into the Church, the priest has no power of "binding and loosing," no authority to absolve you. WHEN you go through Holy Baptism and Holy Chrismation, it is these Sacraments that absolve you, not your confession of sins. So, from all viewpoints - connoisseurs, correct me if I am wrong! - your talking about your sins to your priest while you are not yet a member of the Body of Christ are just spiritual conversation, maybe comforting, maybe helpful, but not absolving. If you commit sins AFTER you have been baptized and chrismated (as we all do), then you must go through the Sacrament, or Holy Mystery, of Confession, and then your priest will exercise his unique authority to "bind and loose."
