Dogmatics describes the deeds of God done for, to, and in human beings; ethics describes what renewed human beings now do on the basis of and in the strength of those divine deeds. In dogmatics human beings are passive; they receive and believe; in ethics they are themselves active agents. In dogmatics, the articles of the faith are treated; in ethics, the precepts of the decalogue. In the former, that which concerns faith is dealt with; in the latter, that which concerns love, obedience, and good works. Dogmatics sets forth what God is and does for human beings and causes them to know God as their Creator, Redeemer, and Sanctifier; ethics sets forth what human beings are and do for God now; how, with everything they are and have, with intellect and will and all their strength, they devote themselves to God out of gratitude and love. Dogmatics is the system of the knowledge of God; ethics is that of the service of God. The two disciplines, far from facing each other as two independent entities, together form a single system; they are related members of a single organism. —Herman Bavinck, Reformed Dogmatics
