Marcion redivivus?

I begin to understand why Boyd has been accused of Marcionism when I read at the start of chapter 8:

The problem of relating the Old and New Testaments is as old as the church itself, and the incongruity of the OT’s violent divine portraits with the nonviolent, self-sacrificial, enemy-embracing agape-love of God revealed in the crucified Christ represents the apex of this challenge.

Gregory A. Boyd, The Crucifixion of the Warrior God: Volumes 1 & 2. Fortress Press, 2017, 335.
Though his subsequent remarks make clear how far such is from his intention. Such thoughts, as I continue my initial reconnaissance of the books, are beginning both to shape some questions for my review to try to answer, and yet at the same time make me impatient to see (in book two I assume) more details of his approach to a solution.
