John 17:3

Captain cited Jesus' prayer to argue Jesus explicitly calls the Father 'the only true God,' excluding himself from being that God in the same sense.

Cited by a Unitarian as the 'only true God' text to exclude Jesus and the Spirit; the host responded that the verse names the Father without negating the Son or Spirit elsewhere.

Quoted by a Muslim as a denial of Jesus' deity, prompting the host to answer with texts he says explicitly call Jesus God.

Brought up by the Muslim caller to stress the Father as 'the only true God'; the host answered by appealing to Trinitarian language about the Father as fountainhead without excluding the Son's deity.

Mentioned by a Muslim caller as a likely anti-Trinitarian text ('the Father alone is God'); used as part of a challenge about whether Christian language refers to person or essence.
