Trinitarian missionaries tell us non-trinitarians we have to believe in their “Triune God”. “God is three persons in one being …” Or “one being in three persons”. Basically 3 in 1. We have all heard it before.
Sometimes we are shown a diagram as explanation.
It’s rather ironic that the trinitarian missionary doesn’t believe in a Triune God as pictured above.
He believes in a Triune God-Man as shown here.
The Trinitarian’s God is not 3 in 1. He is God-Man 3 in 2.
