Trinitarian formula casts doubt on the three being one God
Um, this verse implies the three are distinct, which means they are three beings. Moreover, you either have to admit that the Father isn't mentioned in this verse (which is claimed here to be of a Trinitarian formula), or that “God” is used as a synonym for the Father. Isn't it a bit suspicious that it is used for the Father and not for the Son or the Spirit? If this is Trinitarianism, why isn't the Trinity normally explained as God plus Jesus plus the Holy Spirit? That's how Paul describes it.
