The Bible does not provide further details on deacon Nicolas, who was listed among the first seven deacons. However, several historical sources written by early Christian leaders, such as Irenaeus, Tertullian, Clement of Alexandria, Hippolytus, Epiphanius, and Theodoret, indicate that Nicholas was the founder of the Nicolaitan sect. During the time of John, followers of this sect emerged in cities like Ephesus and Pergamum (Rev. 2:6, 15).
The Nicolaitans were distinguished by their intentional disregard for God’s commandments. Their teachings suggested that one’s actions are inconsequential, emphasizing instead that all God desires is a sincere heart. This kind of doctrine, which makes it easier for individuals to follow their desires, is often embraced by many as a way to quiet their conscience. In the Book of Revelation, we see that Christ detested the immoral practices of the Nicolaitans. Conversely, those who abhor their wrongdoings are loved by God.
But you have this in your favor: You hate the practices of the Nicolaitans, which I also hate.
Revelation 2:6.
