I know it's a strange title. If you read the previous post on theosis, then you know that the only resources are the tools the God has provided through the Church. However, if you are new to Orthodoxy many of the concepts are different than in other forms of Western Christianity. Many forms of Western Christianity view God in a legal sense. He is a divine judge that has been offended and whose wrath needs to be assuaged through some type of punishment. The Church becomes a court room. Yet in Orthodoxy, the metaphors are more medical than legal. The Church is a hospital through which a loving God heals the cancer of our sins so that we might share in His life. Grace is not an object that provides or an attitude, but His very life that He bestows. Yes, I know that these are generalizations, but it can be useful to understanding the differences.
Here are some print & audio resources that I have found helpful:
Clark Carlton, The Truth
Clark Carlton, The Life
Conciliar Press booklet on Theosis
also check out Matthew Gallatin's recent podcasts on Imputed Righteousness at Ancient Faith Radio. There are at least 12 episodes, and I think they are provided them all on CD if you don't want to download them all. Click here.
