Thus, Sir, is your holiness, by you described; which holiness you aver is that, which is the great and only design of Christ to promote both by his life and glorious gospel.
To take therefore your description in pieces, if happily there may be found ought, but naught therein.
1. 'It is (say you) an healthful complexion of soul, the purity of the human nature,' &c.
Ans. These are but words; there is no such thing as the purity of our nature, abstract and distinct from the sinful pollution that dwelleth in us (Rom 7:24). It is true, a man may talk of, and by argument distinguish between nature and sin; but that there is such a principle in man (since Adam's fall) a principle by which he may act, or that Christ's whole gospel-design is, the helping forward such a principle, is altogether without scripture or reason. There is no man by nature, that hath any soundness in him (Isa 1:6), no, neither in soul or body; his understanding is darkened, his mind and conscience is defiled (Titus 1:15), his will is perverted and obstinate (Eph 4:18). 'There is no judgment in his goings' (Isa 59:6-10). Where now is the sound and healthful complexion of soul? Let the best come to the best, when we have mustered up all the excellences of the soul of man, as man, shall nought we find there, but the lame, the blind, the defiled, the obstinate and misled faculties thereof. And never think to evade me by saying, the graces of the Spirit of God are pure: for with them you have nothing to do; your doctrine is of the sound complexion of soul, the purity of the human nature, a habit of soul, and the holiness we lost in Adam, things a great way off from the spirit of grace, or the gracious workings of the spirit. You talk indeed of a divine or godlike nature,[1] but this is still the same with your pure human nature, or with your sound complexion, or habit of soul; and so must either respect man, as he was created in the image or likeness of God, or else you have palpable contradiction in this your description. But it must be concluded, that the divine nature you talk of, is that, and no other than the dictates of the human nature, or your feigned purity thereof; because you make it by your words the self same; it is the purity of the human nature, it is a divine or Godlike nature.
2. But you proceed to tell us of a degree, it is so sound and healthful a complexion or temperature of the faculties, qualities, or virtues of soul, 'as maintains in life and vigour whatsoever is essential to it, and suffereth not anything unnatural to mix with that which is so.'[2]
Ans. If, as was said before, there is no soundness of soul in man, as man, and no such thing as a purity of our nature, abstract from that which is sin; then where shall we find so healthful a complexion, or temperature of soul, as to maintain in life and vigour whatsoever is essential to it, and that suffereth not any thing unnatural to mix with that which is so?
But let us take Paul's definition of a man; 'There is none righteous, no, not one: there is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips: whose mouth is full of cursing and bitterness: their feet are swift to shed blood: destruction and misery are in their ways: and the way of peace have they not known: there is no fear of God before their eyes' (Rom 3). I the rather give you this of Paul, than any of my own; because it is the soundest complexion of soul, that the Holy Ghost himself could draw. Here is now no purity of the human nature, nor such sound complexion of soul as can keep itself from mixing with that which is contrary to itself. And note, that this is the state of all men, and that as they stand in themselves before God: wherefore together, even altogether, all the men in the world, take them in their most pure naturals, or with all the purity of humanity, which they can make, and together, they still will be unprofitable, and so much come short of doing good, 'that every mouth might be stopped, and all the world become guilty before God' (v 19).[3]
3. But proceeding, you say, that this complexion is so forcible as to 'keep his supreme faculty (I suppose you mean the conscience) in its throne, (and that) brings into due subjection all his inferior ones, (as namely) his sensual imagination, brutish passions and affections.'[4]
Ans. These words suppose that it is within the power of a man's own soul, always to keep sin out of itself, and so guilt out of the conscience; albeit the scripture saith, that both the mind and it are defiled with the filth of sin, in all whoever do not believe the gospel, with which belief this description meddleth not (Titus 1:15).
They suppose that this conscience is perfectly clear and light, when the scriptures say they have the understanding darkened; yea and farther, in despite of these your sayings of the sound complexion of soul, of the purity of human nature, and of this supreme faculty, the scriptures teach, that man in his best estate is altogether vanity, that they are darkness and night, &c. (Eph 4:18,19; 1 Thess 5; Psa 39:5).
