Perhaps it is always a good idea to use the directions of a good, kind, erudite priest when you study the Fathers. They are not infallible, you know. They do contradict each other. Certain things that they thought and wrote about are pure fantasy from the point of view of the modern natural science (e.g., forming of the body of Christ from the blood of the Most Holy Theotokos). We certainly should not make ourselves an idol of them, and our clergy is most certainly helpful in sorting out what the Fathers really say, what is really valuable in their writings and what is not.
