Trinitarians are fond of quoting 2 Corinthians 13:14 as a proof text for the trinity doctrine. It is hardly that. This verse simply mentions the Lord Jesus Christ, God, and the Holy Spirit all in the same sentence. That’s hardly a basis for justifying the trinity doctrine. If anything, it’s a basis for understanding them separately, not combined in an incomprehensible construct of multiple “persons” in a singular “being.”
Interestingly, there are other passages which speak of three divine entities which trinitarians probably wish they could point to in the way they do to 2 Corinthians 13:14, but such passages won’t even serve those purposes.
For example, in the middle of His diatribe against the Pharisees, Jesus mentions in one breath the Teacher, the Father, and the Leader (Matthew 23:8-10). I’m sure the trinitarians wish He’d said the Father, the Son, and the Holy Spirit (though, as we saw above, even that wouldn’t prove anything). The additional problem for Trinitarians in Matthew 23:8-10 is that Jesus is referring to Himself in all three cases, and Isaiah bears Him witness: Jesus is the Teacher (Isaiah 30:20), the Father (Isaiah 9:6), and the Leader (Isaiah 55:4).
