Matthew 22:21 - Ellicott's Commentary On The Whole Bible

Render therefore unto Cæsar. — As far as the immediate question was concerned, this was of course an answer in the affirmative. It recognised the principle that the acceptance of the emperor’s coinage was an admission of his de facto sovereignty. But the words that followed raised the discussion into a higher region, and asserted implicitly that that admission did not interfere with the true spiritual freedom of the people, or with their religious duties. They might still “render to God the things that were His” — i.e. (1), the tithes, tribute, offerings which belonged to the polity and worship that were the appointed witnesses of His sovereignty, and (2) the faith, love, and obedience which were due to Him from every Israelite. The principle which the words involved was obviously wider in its range than the particular occasion to which it was thus applied. In all questions of real or seeming collision between secular authority and spiritual freedom, the former claims obedience as a de facto ordinance of God up to the limit where it encroaches on the rights of conscience, and prevents men from worshipping and serving Him. Loyal obedience in things in different on the part of the subject, a generous tolerance (such as the Roman empire at this time exercised towards the religion of Israel) on the part of the State, were the two correlative elements upon which social order and freedom depended. Questions might arise, as they have arisen in all ages of the Church, as to whether the limit has, or has not, been transgressed in tins or that instance, and for these the principle does not, and in the nature of things could not, provide a direct answer. What it does prescribe is that all such questions should be approached in the temper which seeks to reconcile the two obligations, not in that which exaggerates and perpetuates their antagonism. Least of all does it sanction the identification of the claims of this or that form of ecclesiastical polity with the “things that are God’s.”
