The context of that sarcastic remark is... That Baha'is believe the Bible is from God. And usually, I divide the Bible into two parts, the Hebrew Bible and the NT, because Jews have their own interpretation concerning their Scriptures. But, this is about Christians and Baha'is. The Baha'is interpret the Bible to say something completely different than what Christians believe it to be saying. The "old geezer" part is that Jesus wrote nothing. We are depended on what his followers told us about him. How accurate are they? Next, the early church leaders had to decide which books got into the NT. Did they get it right? Then, through the centuries, "old geezers" have told us all what to believe about the Bible. And now, what do we do with this guy, Baha'u'llah, that says he is the return of Christ? Here we are in the future. Did he fulfill the prophecies?
