Don't take this the wrong way because I love ya, man....big time. But I'd say that you might be taking your talent as a writer or debater and using it without a mandate from the Lord. As others have said, entering the Orthodox faith you have a massive new world of spirituality, history, ikonography, theology, discipline, contemplation, and study to soak yourself in. You're not even Orthodox yet and you're debating as Orthodox against the non-Orthodox. Hyperdoxy is the worst ailment of the noob novice in Orthodoxy.
Is it God's will and desire for you right now to writer letters to Mr. Hall and his folks? Is debating Calvinists your own fallen drive or from God?
When I first went into Orthodoxy, I noticed there was no Orthodox presence in my city here. Immediately I thought it was my job to try and get that going. I was passionately asking my priest and folks at my church about it and wanting to get something going. Our then-deacon who is now a wonderful friend at our parish to me said, "Is it the Lord's will that there be a Church in Visalia, CA at this time? Did He reveal that to you in prayer? Did the Bishop feel this same way?" It dawned on me that I was just hyperdox, on fire, excited, and I wanted to shout from the rooftops about how Orthodoxy was the greatest thing since sliced bread to everyone. But just because I feel like shouting doesn't mean the Lord wants me shouting.
Humility and learning in quiet stillness is the Orthodox way. I wish I had known that when I came in. I came into Orthodoxy like a man on fire. These days debating Catholics online or Calvinists, it just does nothing.
In prayer I have felt my vocation in Orthodoxy is
a) being the best dad I can be
b) being the best husband I can be
c) being the best reader at church possible
d) trying my best to be an effective teacher
e) TO LEARN.....
I just don't debate much. Heck, these days I don't even debate much here in TAW with posters who I see as seriously in error or misguided. I just don't feel a calling.
Back in the Catholic Church days, I was a guitar-player in our 10:30am Mass band. I am a good guitarist. But after I realized that strumming a guitar wasn't really right, that church isn't Sgt. Pepper, that the ancient liturgy was not Woodstock and that instruments weren't the focus or part of the equation, I got out of that.....Maybe just because you're a good writer doesn't mean you're called at this moment to go debating, arguing, and kicking butt. You're in the learning and growing phase.....
I am here today, believing in Orthodox theology and waiting for the green light to go from the Lord precisely because when I was posting my Calvinist diatribes against the Church, some people enlightened me out of my ignorance in the same manner - debate. Mr. Hall and his ilk are in darkness and need someone to respond to them. I am a writer. I have won awards for my writing and have been published in a national magazine. It's what I do. It's my gift, and I intend to use it without apology.
I have prayed for Mr. Hall, that his eyes be opened. May my efforts help to achieve this if God will use them.
