Notes: Titus 3:10

Reject a factious man after a first and second warning,
(Titus 3:10)

So serious are the problems that may occur, Paul advises Titus to reject, or remove from fellowship, one who engages in heretical discussions after he has been warned up to two times.

There are those within the church who love to spread dissension and strife by “asking simple questions” or “desiring to engage in conversation” regarding false teaching.

Paul would have none of this.  Put them out of the church.
