This utterly confused meme is referring to the hoary myth that the canon of the Bible was voted on at the Council of Nicaea in 325 AD and even helpfully includes an image of an icon depicting the Emperor Constantine and key figures from that Council holding a copy of the Nicene Creed formulated by the assembled bishops at Nicaea. Alarmed at his success, other Christian leaders began to preach and write vigorously against Marcion’s ideas and it seems that his canon of eleven works inspired anti-Marcionite Christians to begin to define which texts were and were not Scriptural.
