In his 1999 debate against Muslim Hamza Adbul Malik, Reformed Baptist (and longstanding anti-Mormon) James R. White said the following about 1 Tim 6:16:
In 1
Timothy 6:16, it talks about no one has seen this unapproachable light, it
doesn't say they haven't seen the person, but the unapproachable light, that
passage may actually be about the Lord Jesus Christ in fact. (Beginning at the 1:09:20 mark)
This is important as many of his fellow
Evangelical anti-Mormon activists (e.g., Matt Slick) have used 1 Tim 6:16 to teach
that the person of the Father cannot be seen, but White notes that the text
is not speaking of the person in view (whether it be the Father or even
Jesus as he is open to in the above) but the light.
