“The Church is a divine religious institution of the New Testament, built by our Savior Jesus Christ through His incarnate Dispensation…In this institution is entrusted the totality of revealed truths; in it operates Divine grace through the Mysteries; in it are regenerated those, who with faith, approach Christ the Savior; in it has been preserved both the written and the unwritten Apostolic teaching and tradition.”

(St Nectarios of Aegina, quote from ‘Writings of Orthodox Saints’)
