Paired with John 14:16 by a Muslim guest to identify Muhammad as the Spirit of truth, though the host rejects that reading after examining the context.
Scripture spotlight
John 16:13
bible
13 However when he, the Spirit of truth, has come, he will guide you into all truth, for he will not speak from himself; but whatever he hears, he will speak. He will declare to you things that are coming.
Used against modalism to argue that the Holy Spirit is personally distinct, since he does not speak on his 'own authority' but on another's.
This verse was used against a Oneness/modalist view: the Spirit 'will not speak on his own authority' and 'will hear,' so the hosts argued the Spirit is personally distinct from the Father.
Cited by a Muslim guest to argue that the coming figure 'he will hear and speak' matches Muhammad receiving revelation; the host rejected this and treated the passage as about the Holy Spirit.
Quoted because the Spirit 'will not speak on his own' but only what he hears; this was used to argue the Spirit is a distinct personal subject, not Jesus speaking as another mode.
