Deuteronomy 6:4
Douay-Rheims
Hear, O Israel, the Lord our God is one Lord.
Augustine of Hippo
That Trinity is one God. Not that Father, Son and Holy Spirit are identically the same. But the Father is Father, the Son is Son, and the Holy Spirit is Holy Spirit, and this Trinity is one God, as it is written: "Hear, O Israel, the Lord your God is one God."
