Thanks everybody for your input. Much appreciated. I've been able to access a lot of material on the Internet on the subject. I listened to the podcast by Fr Tom Hopko too. And while he's not exactly characterised by the conciseness of his talks, he did make some very good points.
It's also been refreshing to find a good "tone" on this forum. There are some forums that I've looked at in the past where people seem intent on proving everyone else wrong, and they're not pleasant places to be. That does not seem to be the case here - so I look forward to sharing with you all into the future!
Garanita--I am reading a book by two Evangelical Protestant theologians that back up what other posters have told you. It is "The Heresy of Orthodoxy: How Contemporary Culture's Fascination with Diversity Has Reshaped Our Understanding of Early Christianity" by Andreas Kostenberger and Michael Kruger. Andreas J. Köstenberger is Director of Ph.D. Studies and Professor of New Testament and Biblical Theology at Southeastern Baptist Theological Seminary (Southern Baptist) in Wake Forest, North Carolina. Michael Kruger is Associate Professor of New Testament and Academic Dean at Reformed Theological Seminary (mainly Presbyterian/Reformed) in Charlotte, North Carolina.
Reading this book, it was amazing to read that the authors concur with the view of Christian orthodoxy that they attributed to Father John Behr, the Dean of Saint Vladimir's Orthodox Theological Academy, the flagship seminary of the Orthodox Church in America.
