The Orthodox Church is a "hospital for the soul". We come to confess our sins and our troubles and place them in the hands of Our Lord Jesus Christ for forgiveness and healing. It is a community of repentant sinners who gather together to meet Christ in the Eucharist, a gathering or "ekklesia". We are in community with the saints, living and passed over - the church militant and church triumphant, forming together the one body of Christ, who is its Head.
A concise description of our understanding of the nature of sin can be found here.
