The Gospel this week is from Matthew 22:15-21.
God's plan for man on earth was that he should live in the society of his fellowmen. Society must be governed, there must be authority which will direct the actions of the component members toward the common good, which common good is principally, though not exclusively, the material welfare of the members as a whole. As his ultimate end, however, man has his spiritual welfare. This government, this temporal power to rule and direct the human groups or societies or states, comes, therefore, from God for it is his will that such societies should exist. The answer of our Lord explicitly restates this fundamental norm of the divine natural law. "Give to Caesar what is Caesar's;" the state authorities have a right to the obedience and cooperation in all things that tend to the material welfare of the state, provided always the spiritual welfare of the members is not impeded by the rulers' demands.
As a partly spiritual being man is destined to be a citizen of a spiritual eternal kingdom, and while on this earth he has the duty and the possibility of preparing himself for citizenship in that kingdom. And since this kingdom is of a higher and much more important nature, man's primary aim in life must be to reach that kingdom. He must, in other words, find out and fulfill his duties toward God; he must "give to God what is God's."
This dual citizenship of man and the dual obligations that arise from it are the common knowledge of all from the natural law but are made more explicit still in divine revelation of which today's answer, given by Christ to the Pharisees, is a precise and perfect resume. We have duties to God and duties to our country and the fulfillment of the latter is part of the fulfillment of the former. We Christians have no doubts as to our obligations under these two headings. We fulfill our duties to God by being faithful, loyal, active members of the spiritual kingdom, the Church, which Christ established on earth in order to lead us to our eternal kingdom. We fulfill our duties to our country by loyally obeying the just laws of the State, by paying all lawful taxes, and by contributing our share, whenever called on, toward the common good.
Both St. Peter (1 Pet. 2: 13-14) and St. Paul (Rom. 13: 1-7), stressed the obligation on the early Christians of being an example to all in their loyalty as citizens of the state. The same necessity obliges us too. We who know the divine, positive and natural law so much better than many others, must help to enlighten those others by our faithful observance of these laws. And our loyalty, too, will give the lie to those enemies of the faith who, in their ignorance and foolish opposition to things spiritual, are only too ready to think that loyalty to our Church and our God must of necessity make us disloyal to our country. History already has given the lie to such calumnies, for the loyal Christian has ever been the loyal citizen, but we must keep on writing such history in glaring lights of daily deeds, for there are, and there always will be, those enemies who cannot read history books.
