Gaius

In the time of Zephyrinus, bishop of Rome, that is, in the reign of Antoninus, the son of Severus, Gaius held a very notable debate Against Proculus, a follower of Montanus, convicting him of rashness in his defense of the new prophecy. In the same volume he also counts only thirteen letters of Paul and says that the fourteenth, the one now called To the Hebrews, is not his. And among the Romans to this day it is not considered to be the work of the apostle Paul. [a]
