There is a very interesting volume in the writings of George Florovsky. He was an Orthodox priest who taught at St. Vladimir's Seminary, Harvard and Princeton Seminary.
His volume one is a must for an understanding of how the Eastern Church viewed Tradition in the early centuries. In fact, I would like to see all of his volumes available in Logos. From memory...I believe there are twelve of them. The entire set is no longer in print. In volume one he deals with St. Vincent of Lerins and other early Christian writers like Tertullian, Irenaeus and Augustine.
Christ is risen!
