Mark Jones draws attention to
The Economy of the Covenants Between God and Man by Hermann Witsius (1636-1708), from which I make a note of the following:
The Scriptures represent the Father, in the economy of our salvation, as
demanding the obedience of the Son even unto death, and, upon condition of that
obedience, promising him in his turn that name which is above every name, even
that he should be the head of the elect in glory; but the Son, as presenting
himself to do the will of the Father, acquiescing in that promise, and in fine,
requiring by virtue of the compact, the kingdom and glory promised to him. When
we have clearly demonstrated all these particulars from Scripture, it cannot,
on any pretence, be denied, that there is a compact between the Father and the
Son, which is the foundation of our salvation. (2.2.2)
I consider three periods, as it were, of this covenant. Its commencement
was in the eternal counsel of the adorable Trinity: in which the Son of God was
constituted by the Father, with the approbation of the Holy Spirit, the Saviour
of mankind; on this condition, that, in the fulness of time, he should be made
of a woman, and made under the law; which the Son undertook to perform. (2.3.2)
The second period of this covenant I place in that intercession of
Christ, by which, immediately upon the fall of man, he offered himself to God,
now offended, in order actually to perform those things to which he had engaged
himself from eternity; saying, thou hast given them to me, and I will make
satisfaction for them: and so he made way for the word of grace to be declared
to, and the covenant of grace to be made with them. (2.3.3)
The third period of this covenant is that, when, on his
assuming human nature, he suffered his ears to be bored; compare Ps. 40:7, with
Heb. 10:5; that is, engaged himself as a voluntary servant to God, from love to
his Lord the Father, and to his spouse the church, and his spiritual children
(for the ears of such voluntary servants were bored, Ex. 21:5, 6), was
"made under the law," Gal. 4:4, by subjecting himself to the law:
which he solemnly testified by his circumcision on the eighth day after his
birth, whereby he made himself "a debtor to do the whole law," Gal.
5:3. (2.3.4)
The Son, as God, neither was, nor could be subject to
any law, to any superior; that being contrary to the nature of Godhead, which
we now suppose the Son to have in common with the Father. "He thought it
no robbery to be equal with God." No subjection, nothing but the highest
super-eminence, can be conceived of the Deity. In this respect he is "King
of kings, and Lord of lords." 1 Tim. 6:15. The emperors Gratian,
Valentine, and Theodosius said, long ago, that "he is a true Christian,
who believes that the Deity of the Father, Son, and Holy Ghost, is one in equal
power; that, under the same majesty, there is one Deity; and he who teaches the
contrary is a heretic;" (2.3.6)
Nor is it any objection against this, that the Son,
from eternity, undertook for men, and thereby came under a certain peculiar
relation to those that were to be saved. For, as that engagement was nothing
but the most glorious act of the divine will of the Son, doing what none but
God could do, it implies therefore no manner of subjection: it only imports
that there should be a time when that divine person, on assuming flesh, would
appear in the form of a servant. And by undertaking to perform this obedience,
in the human nature, in its proper time, the Son, as God, did no more subject
himself to the Father, than the Father with respect to the Son, to the owing
that reward of debt, which he promised him a right to claim. All these things
are to be conceived of in a manner becoming God. (2.3.7)
But since in Christ, as Mediator, there is an union of the divine and
human natures, this difficulty remains to be discussed, whether both natures
were in some measure subject to the law. We may easily affirm this of the
human, as we have already so often shown; but it seems, from what we have
confirmed [2.3.6], it must be denied with respect to the divine. However, as the
human nature does not, without the divine, complete the person of the Mediator,
it does not appear that the Mediator, as such, did not engage to be subject to
the law, without bringing his divine nature likewise to share in that
subjection. (2.3.16)
In order to remove this difficulty, we are accurately to
distinguish between both natures, considered separately, and the same natures
united in the person of God-man. It was proper, that both natures should act
suitably to themselves and their distinct properties. Since the divine nature,
as subsisting in the Son, could not truly and really be subject; therefore, by
virtue of the covenant, it did not exert or display all its majesty, in the
assumed form of a servant; nor hinder that nature, to which it was united by
the hypostatical union, from being truly subject to the law, both as to the
condition of the reward, and as to the penal sanction; which, indeed, was
neither a real renunciation nor degradation of the divine superiority, but only
a certain economical veiling of it for a time. (2.3.17)
We commonly ascribe to the person, God-man, the relation of an inferior
to a superior, by a constitution or appointment; that, both by doing and
suffering, those things might be accomplished, according to the condition of
each nature, which were requisite to our salvation: so that the very obedience
and sufferings themselves, are not only to be appropriated to the human nature,
but to be considered as truly performed and suffered by the God-man. If this
were not the case, they would not be of infinite value and dignity, nor
sufficient for our redemption. Hence he, who is "in the form of God,"
is said to have "made himself of no reputation, and became obedient unto
death," Phil. 2:6, 7, 8; and to be the Lord of glory, who was crucified, 1
Cor. 2:8. (2.3.19)
It is here usual to inquire, whether Christ, as Mediator, is inferior to
the Father and subordinate to him. But this controversy, it seems, may be
easily settled among the orthodox: if the Mediator be considered in the state
of humiliation and the form of a servant, he is certainly inferior to the
Father, and subordinate to him. It was not of his human nature only, but of
himself in that state, that he himself said, John 14:28. "The Father is
greater than I." Nay, we may look upon the very mediatorial office in
itself, as importing a certain economical inferiority or subordination; as
being to be laid down, when all things shall be perfectly finished, and "God
himself shall be all in all," 1 Cor. 15:28. Nevertheless this undertaking
and mediation, and the bringing of fallen man to God, to grace, and glory, is
not so much beneath the excellency of the Deity, but we may, without the least
hesitation, affirm, that this glory of mediation is incommunicable to any
creature. It is the glory of Jehovah to be the righteousness of Israel. This
glory he gives to none who is not God: to be Mediator does not merely denote a
servant of God, but the great God and Saviour; who, as the first and principal cause of
saving grace, equal to the Father, works by his own power, our reconciliation
with God, by means of the subjection and obedience of his human nature, without
which the co-equal Son could neither perform his service, nor obey the Father. (2.3.20)
