Hi Pensteel,

No, the book of John does not teach the doctrine of the Trinity. Trinitarians love to use the doctrine of the Trinity to prove the doctrine of the Trinity. Please read my post about how they go about doing this.

If you let scripture interpret scripture instead of reading the doctrine of the Trinity into it, you will find out they none of the disciples believed in such a doctrine.

If you have any questions, please bring them up and let's look at the verses in the light of other verses.

Regards,
Malachi
