For the last few years, Dale Tuggy has been laboring to fire up a theological revolution from the wet kindling of "Christian unitarianism". Dale imagines that the OT precludes the Trinity and the deity of Christ. But he's stuck with the NT.
Fact is, it would be so much simpler for him to be a Jewish unitarian rather than a "Christian unitarian". Given his view of OT monotheism, it would be far more logical for him to take the position of Maimonides and other Orthodox Jews who regard Christianity as a heretical sect, who regard the NT as heretical sectarian offshoot of Judaism. Ironically, Orthodox Jews interpret the NT much better than "Christian unitarians", while Christian Trinitarians interpret the OT much better than Orthodox Jews.
