Finney’s Theology?
One need go no further than the table of contents of his Systematic Theology to learn that Finney’s entire theology revolved around human morality. Chapters one through five are on moral government, obligation, and the unity of moral action; chapters six and seven are "Obedience Entire," as chapters eight through fourteen discuss attributes of love, selfishness, and virtues and vice in general. Not until the twenty-first chapter does one read anything that is especially Christian in its interest, on the atonement. This is followed by a discussion of regeneration, repentance, and faith. There is one chapter on justification followed by six on sanctification. In other words, Finney did not really write a Systematic Theology, but a collection of essays on ethics.
But that is not to say that Finney’s Systematic Theology does not contain some significant statements of theology.
First, in answer to the question, "Does a Christian cease to be a Christian, whenever he commits a sin?", Finney answers:
"Whenever he sins, he must, for the time being, cease to be holy. This is self-evident. Whenever he sins, he must be condemned; he must incur the penalty of the law of God ... If it be said that the precept is still binding upon him, but that with respect to the Christian, the penalty is forever set aside, or abrogated, I reply, that to abrogate the penalty is to repeal the precept, for a precept without penalty is no law. It is only counsel or advice. The Christian, therefore, is justified no longer than he obeys, and must be condemned when he disobeys or Antinomianism is true ... In these respects, then, the sinning Christian and the unconverted sinner are upon precisely the same ground (p. 46)."
Finney believed that God demanded absolute perfection, but instead of that leading him to seek his perfect righteousness in Christ, he concluded that "... full present obedience is a condition of justification. But again, to the question, can man be justified while sin remains in him? Surely he cannot, either upon legal or gospel principles, unless the law be repealed ... But can he be pardoned and accepted, and justified, in the gospel sense, while sin, any degree of sin, remains in him? Certainly not" (p. 57).
Finney declares of the Reformation’s formula simul justus et peccator or "simultaneously justified and sinful," "This error has slain more souls, I fear, than all the Universalism that ever cursed the world." For, "Whenever a Christian sins he comes under condemnation, and must repent and do his first works, or be lost" (p.60).
