You’re preaching to the choir. Orthodox believe praying to their dead gets them a reprieve on the last day. And yes this includes hell. What’s the most “radical” position? Catholic’s purgatory, where all are eventually going to heaven, or the Orthodox, where prayers can get you out of hell? I rest my case.
The Orthodox refer to your doctrine of Purgatory as “sophistry.” It is not a beleif of the early church, otherwise they’d share it with you. It’s just another Roman novelty.
