[1st.] That the obedience that Christ yielded to the
law in general, is not only to the peculiar law of the mediator, though he
yielded it as mediator. He was incarnate as mediator, Heb. ii. 14; Gal. iv.
4; and all he afterward did, it was as our mediator. For that
cause “came he into the world,” and did and suffered whatever he did or
suffered in this world. So that of this expression, as mediator,
there is a twofold sense: for it may be taken strictly, as relating solely
to the law of the mediator, and so Christ may be said to do as mediator
only what he did in obedience to that law; but in the sense now insisted
on, whatever Christ did as a man subject to any law, he did it as mediator,
because he did it as part of the duty incumbent on him who undertook so to
be.
