ACC ~ John 5 v31

A WITNESS DOES NOT TESTIFY ABOUT HIMSELF

TERTULLIAN: No one who comes on the authority of another establishes that authority as his own but rather guards against such an understanding, for first must come the support of the one who gives him his authority. Now, [Christ] will not be acknowledged as Son if the Father never called him this. Nor will people believe he is the sent One if no sender gave him a commission. AGAINST MARCION 3.2. [1]
