The present volume, in its treatment of Ethical Monism, Inspiration, the Attributes of God, and the Trinity, contains an antidote to most of the false doctrine which now threatens the safety of the church. I desire especially to call attention to the section on Perfection, and the Attributes therein involved, because I believe that the recent merging of Holiness in Love, and the practical denial that Righteousness is fundamental in God’s nature, are responsible for the utilitarian views of law and the superficial views of sin which now prevail in some systems of theology. There can be no proper doctrine of the atonement and no proper doctrine of retribution, so long as Holiness is refused its preëminence. Love must have a norm or standard, and this norm or standard can be found only in Holiness. The old conviction of sin and the sense of guilt that drove the convicted sinner to the cross are inseparable from a firm belief in the self-affirming attribute of God as logically prior to and as conditioning the self-communicating attribute. The theology of our day needs a new view of the Righteous One. Such a view will make it plain that God must be reconciled before man can be saved, and that the human conscience can be pacified only upon condition that propitiation is made to the divine Righteousness. In this volume I propound what I regard as the true Doctrine of God, because upon it will be based all that follows in the volumes on the Doctrine of Man, and the Doctrine of Salvation. The universal presence of Christ, the Light that lighteth every man, in heathen as well as in Christian lands, to direct or overrule all movements of the human mind, gives me confidence that the recent attacks upon the Christian faith will fail of their purpose. It becomes evident at last that not only the outworks are assaulted, but the very citadel itself. We are asked to give up all belief in special revelation. Jesus Christ, it is said, has come in the flesh precisely as each one of us has come, and he was before Abraham only in the same sense that we were. Christian experience knows how to characterize such doctrine so soon as it is clearly stated. And the new theology will be of use in enabling even ordinary believers to recognize soul-destroying heresy even under the mask of professed orthodoxy.
