Hardy:
Dual Aspect of the death of Christ:
1) In regard of Christ, the certain continuance of all the true members of the church depends upon the energy of his death, and the efficacy of his intercession.
[l.] Though the design of Christ’s death was in some respect general, namely, to purchase a possibility of salvation for all upon the conditions of faith and repentance, yet I doubt not to assert, that besides this there was a particular design of his death, which was to purchase a certainty of salvation by faith and repentance for some, to wit, the elect, this being the most rational way of reconciling those scriptures which do enlarge Christ’s death to the whole world, with those that restrain it to his church. Indeed, if there be not some who shall be actually saved by Christ’s death, his death will be in vain. If there be not some for whom Christ hath purchased more than a possibility of salvation upon condition, it is possible none should be actually saved by it, especially if (as those who deny this peculiar intention affirm) the performing of the condition depends so on the liberty of our will, that notwithstanding the influence of grace a man may choose or refuse to do it; for then it is as possible that every man may not believe as that he may, and consequently it is possible no man may be saved by Christ’s death, and so Christ’s death in vain, as to that which was its primary end, and consequently his intention frustrated. It remaineth, then, that as Christ intended his death to be sufficient for all, so that it might be efficient to some, in order to which it was necessary that for those persons he should purchase grace, yea, not only grace, but perseverance in grace till they come to glory.

Christ sustained and equivalent satisfaction:
1) This punishment thus inflicted on Christ, is a plenary satisfaction to God’s justice. It is true, this word satisfaction is not formally expressed in Scripture, yet there are equivalent phrases. Such, among others, is that phrase so often used of redeeming; and as if the Holy Ghost would prevent that Socinian exposition of (redimere pro aliquo modo liberare) redeeming, as if it were only in a large sense no more than delivering, it is St Paul’s express phrase, ‘Ye are bought with a price,’ 1 Cor. vi. 20; and that this price may appear to be of full value, it is opposed to,
and advanced above, corrupt gold and silver by the apostle Peter, 1 Peter i, 18, 19. Nor is it any infringement to the merit of this price and worth of this satisfaction, that the suffering of Christ was not every way the same that we should have undergone, since it is all one whether the debt be paid in the same coin or no, so it be to the full value. Christ sufffered the punishment of our sins, as Calovius well observeth, [Vide Calov. Sociniania. Prot.], though not secundum identitatem omnimodam, yet per aquivalentiam, the same in every respect, yet equivalent to it. Indeed, what satisfaction could justice demand more than infinite; and the sufiering of an infinite person could not be less. Nathanael Hardy, The First General Epistle of St John the Apostle, Unfolded and Applied (Edinburgh: James Nichol, 1865), 114. [Footnotes cited inline, italics original, underlining mine.]
Sins of the world:
1) Finally, when secure sinners hear of the infinite merit of Christ’s blood, how satisfactory it is for the sins of the whole world, and therefore much more of a particular person, they are willing to persuade themselves of an interest in that blood, and thereby of reconciliation and fellowship with God, not considering what our apostle saith in the very next verse, the blood of Jesus Christ cleanseth from all sin; but it is only those who walk in the light. Nathanael Hardy, The First General Epistle of St John the Apostle, Unfolded and Applied (Edinburgh: James Nichol, 1865), 61.
