I just signed up for Abouna Justin Rose's "Byzantine Perspective on Social Justice" course offered by the Seminary.
I'm impressed with his "Come, Follow Me" book which we are using this year for our parish "All Generations" religious ed program. The chapters are short, easy to follow and build Eastern Christian spirituality.
