Authority bears no relation to truth.

The Catholic Answers

It bears a tremendous relation to truth. The whole system of educating to truth supposes authority in a body of teachers. God is truth itself and the source of all truth. When God speaks, what He says has authority, and the authority of His words is an absolute guarantee of the truth of what He says.
