I'm not sure why this conversation has turned to a discussion of me. Though I understand that you are using my example as a means of attempting to expose problems in Dave's theology (from your perspective).
To be clear about what I embraced: I was raised in an Episcopal home. We attended church regularly and I also attended Sunday School. So I was familiar with Christian doctrine -- at least the essentials. In high school, when I actively turned to Christ as my personal savior, rather than the more abstract "savior of the world" that was the background of my cultural upbringing, I did so with the understanding that he was the Son of God who had died on the behalf of sinful, fallen humanity, in order that we might have eternal life with him. I realized at the time that I had not given my heart, consciously and passionately, to him before; rather, I had been taught about him. Now, at a time of extreme duress, when I could clearly see my own weakness and error, I turned to him and asked him to save me -- to be the Lord of my life. I was not a Bible scholar. I didn't know Greek or Hebrew. I couldn't skillfully exegete scripture. But I knew the gospel message; I knew who the gospel claims Christ is (the son of God become flesh who died for the sins of the world). And that is who I turned to. God the Father and Christ His son. I didn't know, and could not have explained, the fine doctrinal differences between Episcopal and Catholic and Lutheran denominations.
I expect, in this regard, I was no different from many, many people who first embrace Christ and become "saved." I was not a Bible scholar but I knew the gospel message.
I give this testimonial because I am tired of the old argument that anyone who leaves Christianity was never a Christian. I think this is a fallacious argument.
