'Sect' in the Bible

For we have found this man to be a troublemaker, one who stirs up riots among all the Jews throughout the world, and a ringleader of the sect of the Nazarenes.

But I confess this to you, that I worship the God of our ancestors according to the Way (which they call a sect), believing everything that is according to the law and that is written in the prophets.

But we would like to hear from you what you think, for regarding this sect we know that people everywhere speak against it."
