"Spiritual knowledge is the state of spiritual theoria, when one sees invisibly and hears inaudibly and comprehends incomprehensibly the glory of God. Precisely then comprehension ceases and, what is more, he understands that he does not understand. Within the vision of the uncreated Light man also sees angels and Saints and, in general, he experiences communion with the angels and the Saints. He is then certain that resurrection exists. This is the spiritual knowledge which all the holy Prophets, the Apostles, Martyrs, ascetics and all the Saints of the Church had. The teachings of the Saints are an offspring of this spiritual knowledge. And, naturally, as we said earlier, spiritual knowledge is a fruit of the vision of God. "THE ILLNESS AND CURE OF THE SOUL" Metropolitan Hierotheos of Nafpaktos [1]
Faith And Science In Orthodox Gnosiology And Methodology by George Metallinos
"The scientist and professor of the knowledge of the Uncreated, in the Orthodox Tradition, is the Geron/Starets (the Elder or Spiritual Father), the guide or "teacher of the desert." The recording of both types of knowledge presupposes empirical knowledge of the phenomenon.
The same holds true in the field of science, where only the specialist understands the research of other scientists of the same field. The adoption of conclusions or findings of a scientific branch by non-specialists (i.e. those who are unable to experimentally examine the research of the specialists) is based on the trust of the specialists credibility. Otherwise, there would be no scientific progress.
The same holds true for the science of faith. The empirical knowledge of the Saints, Prophets, Apostles, Fathers and Mothers of all ages is adopted and founded upon the same trust. The patristic tradition and the Church's Councils function on this provable experience. There is no Ecumenical Council without the presence of the glorified/deified (theoumenoi), those who see the divine (this is the problem of the councils of today!) Orthodox doctrine results from this relationship."
