Are Christian pastors who teach religious tolerance false teachers?

Yes, Christian pastors who teach religious tolerance are false teachers, because they teach against the Word of God.

The Holy Bible is clear that believers are to be intolerant of other religions.

True servant of Jesus Christ will preach against idolatry and against respecting other religions.

All other religions are false religions, so they should not be respected.

That is the position of the Holy Bible.

The Great Commission demands converting people of other religions to Christianity.
