Orthodox tradition differs immensely from 
 non-Orthodox and other religious traditions. In this article we will examine 
 this issue by taking examples from two sciences: astronomy and medicine.
First of all, it should be stressed once more 
 that the Church’s tradition is the experience of the God-seeing saints, 
 Prophets, Apostles and Fathers. They lived this experience by the revelation 
 of God and conveyed it to their spiritual children, and it is recorded in 
 their writings. Thus three factors are very closely linked: the saints who 
 behold God; their illuminated nous, by means of which they share in 
 the experience of revelation; and their writings, in which the experience is 
 recorded in created words and concepts. The basic elements of the tradition 
 are the glorified saints(glorified=theosis), who are the bearers of 
 the tradition.
The Fathers of our Fathers 
 in the Old Testament, the Prophets, had theosis without the human 
 nature of Christ. Afterwards, the Apostles also had theosis, with 
 the human nature of Christ. After Pentecost we have another kind of 
 theosis with the experiences that they have after their initial 
 theosis, because the same experience of Pentecost continues within the 
 Church and has not come to an end. 
 
 Given that the experience of Pentecost has not 
 come to an end, the bishops, who have this experience, are led to the same 
 experience and know what they are talking about.
 
Because of the continuity of this tradition, 
 the Orthodox patristic tradition resembles modern biology, chemistry, 
 astronomy and medical science. In this way, the tradition of the Church is 
 continued empirically. What is this parallel experience? The fact that cures 
 continue and people are cured. People continue to learn the truth from 
 astronomy, medical science, and biology; similarly, in Orthodoxy, from the 
 experience of purification, the experience of illumination, 
 which is the cure of the human personality, and the experience of 
 glorification (theosis), which is the telescope and microscope 
 of Orthodox theology. This is why we believe that we are on the right path 
 and are still within the tradition.
