Curious addressed the "what if it's theological" aspect very well. And, the point where I most adamantly agree is point 1: Name the theological position, the rest also being necessary.
Steve often reminds us that the site is community driven, which seems to be more Nigel's point: The sabbath was made for man, not man for the sabbath.
In my experience, "contradiction questions" ('POV' is my preferred wording) usually go back to the "point of view" issue, that difference (without deep contradiction) is necessary for multiple testimonies in court to prove an event was real. IMHO, that is the answer here, and that was essentially the answer that was marked "correct".
I'll take the minimalist approach so precedent doesn't sprawl. This is the thought I first had a few days ago and it hasn't changed since I let it bake.
It is a hermeneutical answer
The answer gives definitions. Definitions are hermeneutical.
The first verse is about God. That's divine, et cetera.
The second verse is about Jesus. That's human nature, et cetera.
That works for both Trinitarian and Oneness views.
I thought about whether this needed sources, which was my only concern. But, the problem is that the definitions are so self-evident, it would be like asking for a source to claim that a circle is round. These two God and human definitions aren't really definitions; they are more or less reminders that explain it all.
The Bible verses later in the answer satisfy the need for sources and/or research.
Not only is it a great answer, it's probably the most acceptable answer that could be given, and it shows pure hermeneutics at their best.
