Christians had only limited access to bibles until the invention of the printing press in 1493. The source of their unity and faith in the centuries before bibles were available was the oral tradition. Tradition is ‘The Way’ of life, based on Christ’s teachings and sayings, and handed down from the Apostles and their successors. Orthodoxy observes strictly this traditional way of life. Scripture is not open to individual interpretation. It is understood by the Holy Spirit in the Living Tradition of the Church. Scripture compliments and strengthens Tradition, and likewise Scripture requires the dynamic embodiment of Tradition, where the Spirit thrives.
