LOL, are you serious?
That’s an ABSOLUTELY SERIOUS DOCUMENT adhered to by many dedicated and honest Christians who hold exactly to it. If you don’t recognize those names ... I’ll just let you know that they are like (so to speak) “godfathers” in the Christian Evangelical community.
This is as near to a modern-day “Church Council” that you’re ever going to see (in this day and age) - comparable to those who argued and settled the issue of (for instance) the “Diety of Christ” in the old days.
SO ... yes ... this is absolutely serious.
