Orthodox Christianity is not ultimately about history, comparative religion, written doctrine, and external practices. The Orthodox Way is about internal prayer and personal healing through prayer. It is not an academic path, but a practical one. It is about the experience of God and personal transformation through that experience. Human religion based on imagination and opinions don't make you a better person (and can make you a lot worse), but true religion - the spiritual Way - leads to the fullness of Life. God does the work in us if we are willing to cooperate.
Attending a class is not going to change you, but learning about the richness of the spiritual treasure very well may be life-changing. If you take hold the treasure before you, then you will most certainly be on the healing Way.
