Nope. They weren't 4th century either, though if you are a "Bible Believing Christian", you should know that. You should also know why they were condemned. So here's a question for you. Why would you want lurkers here to think that the Nicolaitan heretics were extant in the 4th century and wrote the Creed when that is demonstrably untrue. Is there a point to such foolishness or are you simply attracted to the heresy of the Nicolaitans?
You are the heresey of the nicolaitans. They are the owners of all the churches today.
Real churches meet in homes, not palaces, just like in the first century.
