@JustTheFacts, again, you have no proof that Nicodemus wrote anything in the New Testament but instead rely on your expertise, which is a non-biblical approach. I'm especially sensitive to your approach because of the following:
I grew up in a theologically-liberal or neo-orthodox church that got their pastors from Union Theological Seminary in Chicago. They used their logic and rational powers to reason away the miracles and history of Scripture with allegory, which enabled them to make the Bible say anything they wanted it to with their reason being their extra-biblical source of their truth, not the Bible's.
Then, I attended a Baptist church, where God saved me with a biblical line of reasoning within the realm of Scripture. The Baptists kept saying, "Be saved..., be saved." But I asked myself, "Now that I'm saved, what next?" They didn't seem to have an answer to that question.
We attended what I call a cult for a while, where the charismatic "preacher" added his own intellectual and historical ideas that were not in the Bible to say what it really didn't say. Of course, what he said was the law.
Then, I attended Calvin College as a student, met my wife, and joined the Christian Reformed Church because I felt that its beliefs were the most faithful to the Bible on its own terms. That's why your reliance on your own experience and logic caused red flags for me.
