Thank you for the welcome Michael! As you know that quote is from Athanasius of Alexandria, a wonderful early church father who I believe Pastor Gordon has mentioned on more than a few occasions, and his work is even in audiobook format on SermonIndex!
The desert fathers were very much at the heart of the development of Eastern Christianity. My academic studies of theology have led me to understand that there is a long tradition that is unbroken, but also often unwritten, that threads through the history of the Eastern Church in particular. This treasury is preserved in our monasteries, who are so much a part of the life of the Orthodox Church. For more reading on this subject, I would encourage anyone to look at "Saint Silouan the Athonite" by Saint Sophrony of Essex.
Another great resource if you are interested in the desert fathers is to check out something called The Evergetinos. These are the entire collected sayings of the desert fathers, and there's a lot of them: I have a four volume set that must total 2,500 pages!

Some, but not all of this, is available online in English. I believe all of it is available freely in Greek, here may be a starting point if you can read Greek: https://archive.org/details/Evergetinos
Thank you again for the warm welcome brother!
