'Sect' in the Bible

But some from the sect of the Pharisees who had believed [in Jesus as the Messiah] stood up and said, “It is necessary to circumcise the Gentile converts and to direct them to observe the Law of Moses.”

For we have found this man to be a public menace and one who instigates dissension among all the Jews throughout the world, and a ringleader of the [heretical] sect of the Nazarenes.

But I confess this to you, that according to the Way, which they call a [divisive and heretical] sect, I do worship and serve the God of our fathers, [confidently] believing everything that is in accordance with the Law [of Moses] and that is written in the Prophets;

They have known me for a long time, if they are willing to testify to it, that according to the strictest sect of our religion, I have lived as a Pharisee.

But we would like to hear from you what your views are [that is, exactly what you believe]; for in regard to this sect (Christianity), we are fully aware that it is denounced everywhere.”
