Three gods or one god?No. Yehweh is not (only) the Father, He is the triune God. One 'What;' three 'Whos.' The Father is Yahweh, the Son is Yahweh, the Holy Spirit is Yahweh.
One God, three Persons.
Let's look at His Image, marriage.
Two flesh or one flesh?
One flesh, two persons. Their name? Smith. But there is John Smith, and Jane Smith.
It is quite correct to say that Jane is a Smith, or John is a Smith, but it's quite jarring and fundamentally inaccurate to say that Jane is Smith.
And that's what is happening in the OP.
