One of the distinctive characteristics of the Holy Orthodox Church is its changelessness, its loyalty to the past, its sense of living continuity with the ancient Church. This idea of living continuity may be summed up in one word: Tradition. As St. John of Damascus says, We do not change the everlasting boundaries which our fathers have set, but we keep the Tradition, just as we received it [On the Holy Icons, II, 12]. To an Orthodox Christian, Tradition means the Holy Bible; it means the Creed; it means the decrees of the Ecumenical Councils and the writings of the Fathers; it means the Canons, the Service Books, the Holy Icons, etc. In essence, it means the whole system of doctrine, ecclesiastical government, worship and art which Orthodoxy has articulated over the ages [Timothy Ware, The Orthodox Church, p.204].
