From The Prologue of Ohrid:
If, at times, the dogmas of the Faith seem to be like solid food, first endeavor to fulfill the moral dogmas of Christianity, then the understanding of the dogmas of the Faith will be revealed to you. Inquisitive questioning of higher things without effort regarding the improvement of your life does not bring any benefit.
At one time, the monks of Egypt reflected about Melchisedek and, not being able to come to a clear understanding about the mysterious personality of this ancient king and high priest, invited Abba Copres to their assembly and asked him about Melchisedek.
Upon hearing this, Copres struck himself three times on the mouth and said, “Woe to you Copres! You left that which God commanded you to do and you question that which God does not require of you.” Hearing him, the monks were ashamed and dispersed.
St. John Chrysostom writes, “And, if we adhere to the true dogmas and are not concerned about our behavior, we will not have any kind of benefit; and in the same way, if we concern ourselves about our behavior and neglect true dogmas, we will receive no benefit for our salvation. If we want to be delivered from Gehenna and to gain the kingdom, we need to be adorned on both sides: correctness of dogmas and honorable living.”
