Orthodox Christians confess in the presence of the priest to acknowledge that our sins, whether we wish to accept it or not, affect the entire faith community on the one hand, and that we cannot “heal ourselves” on the other. The priest is there to help us overcome those things for which we seek forgiveness, to give advice that a friend or neighbor might not be in a position to give, and to bear witness on behalf of the faith community, of which he is the spiritual father, that we have indeed repented and been forgiven by God.
The Holy Eucharist is called the “sacrament of sacraments” in the Orthodox tradition. It is also called the “sacrament of the Church.” The eucharist is the center of the Church’s life. Everything in the Church leads to the eucharist, and all things flow from it. It is the completion of all of the Church’s sacraments—the source and the goal of all of the Church’s doctrines and institutions.
