Have you ever wondered how to maintain an understanding of monotheism in light of the Christian understanding of the triune Godhead? Have you ever wondered about the identity of "YHWH" in the Old Testament? Have you identified YHWH as the first person of the Trinity as many in the Christian tradition have? If so, this book is for you. Many of the early Trinitarian heresies stemmed from a misunderstanding of YHWH in the Old Testament, especially identifying YHWH as one person and not multiple persons. This book addresses issues relating to the identity of YHWH in the Old Testament and makes the bold claim that YHWH is multiple persons in the OT and therefore, Father is YHWH, Jesus is YHWH, and the Holy Spirit is YHWH. This conclusion is based on sound exegesis of OT/NT passages, the early Christian understanding of God in the Old Testament, and the New Testament's identification of Jesus in the identity of YHWH. If identified thus, a Christian reading of the entirety of Scripture will take on new meaning, resulting in a robust Trinitarian interpretation of Scripture.
