While lending credibility to the “Mosiac order” interpretation of Heb 1:10-12, common among Christadelphian interpreters, Harry Whittaker realized that it would result in one holding to the personal preexistence of Jesus:
A good case can be made for the
view that these words are a symbolic prophecy of the passing of the old Mosaic
order (for does not Scripture insist that “the earth abideth for ever”?).
Compare Isa. 50:9 and 51:6, 16. But suppose this be granted, if the “Lord” of
Heb. 1:10 be Christ, the words still require his pre-existence. (Harry
Whittaker, “Some Wrested Scriptures (13),” The Christadelphian 95, no.
