Attributes of God: Justice- Book 2- Chapter 2- Section 9
SECTION IX. – JUSTICE.
GOD IS PERFECTLY JUST.
Justice consists in giving to every one his due. It has been distinguished into Commutative and Distributive. Commutative Justice is fair dealing in the exchange of commodities, and belongs to commerce. Distributive Justice rewards or punishes men according to their actions, and appertains to government. In either view, justice relates to the distribution of happiness, or the means of procuring it, and presupposes a principle or rule to which this distribution should conform, and, according to which, something is due to the parties. Commutative Justice regulates the giving of one means of enjoyment in exchange for another, so as not to disturb the proportion of happiness allotted to each; but Distributive Justice rises higher, and respects the very allotment or distribution of happiness, giving to one, and withholding from another, according to rule. It is in the latter sense only that justice is attributed to God. It implies the existence of moral government; and it is the attribute which secures a faithful and perfect administration of this government.
Some have admitted another distinction, to which the name Public Justice has been given. This determines the character of God’s moral government, and the rules according to which it proceeds. It may be regarded as a question of definition, whether the existence and character of God’s moral government shall be ascribed to his justice or his goodness. As this government tends to the greatest good of the universe, there appears to be no reason to deny that it originates in the goodness of God; and if it be ascribed to his Public Justice, that justice may be considered a modification of his goodness.
In the moral government of God, men are regarded as moral and as sentient beings, and the amount of their enjoyments is regulated with reference to their moral character. The precise adaptation of this is the province of justice. In the blindness of human depravity, men claim enjoyments as a natural right, irrespective of their moral character and conduct. They reject the moral government of God, and seek happiness in their own way. This is their rebellion, and in this the justice of God opposes them. This is the attribute which fills them with terror, and arrays omnipotence against them. The moral government of God must be overthrown, and the monarch of the universe driven from his high seat of authority, or there is no hope of escape for the sinner. He would gladly rush into the vast storehouse of enjoyments which infinite goodness has provided and claim them as his own, and riot on them at pleasure; but the sword of justice guards the entrance. In opposition to his desires, the government of God is firmly established, and justice and judgment are the habitation of his throne. Even in the present world, the manifestations of this government are everywhere visible; and it is apparent that there is a God, a God of justice, who judgeth in the earth; but the grand exhibition is reserved for the judgment of the great day. Conscience now, in God’s stead, often pronounces sentence, though its voice is unheeded; but the sentence from the lips of the Supreme Judge cannot be disregarded, and will fix the sinner’s final doom.
Although there are hearts so hard as to be unaffected by a sense of God’s justice, a right view of this awful and glorious attribute inspires that fear of the Lord which is the beginning of wisdom. An abiding assurance that a just God sits on the throne of the universe, is indispensable to the proper exercise of piety.
