St. Augustine in Confessions

• God works in perichoresis
• if God works in mutual indwelling, then God's sole existence is compatible with the Father, Son, and Spirit all being God
• If the above is true, only one God exists is compatible with the the Father is fully God, the Son has always been fully God, and the Spirit is fully God

∴ only one God exists is compatible with the the Father is fully God, the Son has always been fully God, and the Spirit is fully God
