I second Boyd’s book above. He is a former Oneness and evangelical theologian.
mike << while Acts 2:38 talks about baptism in the name of the Lord Jesus. Therefore, Jesus is the sole person in the Godhead and Father, Son and Holy Spirit are only his titles. They also point to Isaiah 9:5 where one of the titles given to the messiah is “everlasting Father” or " Father-Forever." >>
Short answer on Acts 2:38. First, the word “name” can mean “by the authority of” (see Matt 18:5, 20; 24:5). Acts 4:7 asks “by what power or by what name have you done this?” Peter answers: “by the name of Jesus Christ of Nazareth” (Acts 4:10). Name = authority.
Second, it can’t be giving us an exact formula as the Oneness people claim since the words slightly differ (see Acts 2:38; 8:16; 10:48; 19:5; etc). Jesus, Lord Jesus, or simply Lord, which? The traditional formula used in the Church has been Matthew 28:19 which are not titles since it is Baptism in the name of THE Father, and of THE Son, and of THE Holy Spirit.
Short answer on Isaiah 9:6. The word in Hebrew Abba can mean “origin” or “source”. Jesus is the everlasting source or eternal origin of creation (also Col 1:15-18; Rev 3:14). It is not teaching the Messiah is His own Father. John 17:5 is particularly good. Hebrews 1 is also confusing to them since there is dialogue between Father and Son before the Incarnation. They teach the Father = God nature, and Son = body or human nature of Jesus. So they argue a kind of Nestorianism (two persons) to maintain their “Oneness” belief. But this falls apart with John 17:5 and Hebrews 1 which talk about Father and Son as distinct BEFORE the Incarnation. Also John 1:1-18. And John 14:16 teaches the Holy Spirit is “another Comforter” therefore distinct from Father and Son.
