Early Christians on Caesar and Civil Authority
Early Christians taught that civil rulers have real authority from God, so believers should honor the emperor, pay taxes, and obey lawful government. Justin Martyr, Clement of Alexandria, Irenaeus, Tertullian, and the Apostolic Constitutions all say this in different ways. They also drew a clear line: give Caesar civil duty, but give worship to God alone. Bible passages like Romans 13 and Matthew 22:21 are the main texts behind this teaching.

What did early Christians believe about caesar and Civil Authority?
Early Christian writers taught that civil rulers had real authority from God, so believers should honor the emperor, pay taxes, and obey the law unless obedience would conflict with God. Justin Martyr, Clement of Alexandria, Irenaeus, Tertullian, Theophilus, and later the Apostolic Constitutions all use this basic line, and Paul and the Gospels are the main Bible witnesses behind it. They also kept a sharp limit: Caesar gets civil honor, but worship belongs to God alone.
The evidence is broad and steady across the second and third centuries, though some texts are direct teaching while others are only short comments or Bible retellings. A few cards are about persecution, political titles, or unrelated uses of Caesar, so they are not central to the main answer. Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.

Questions Answered by the Sources

Justin Martyr, The First Apology Supporting witness
...ve been taught by Him. For at that time, some approached Him and asked if one ought to pay taxes to Caesar. He replied, “Tell Me, whose image is on the coin?” They said, “Caesar’s.” Then He responded, “Give therefore to Caesar what is Caesar’s, and to God what is God’s.” Thus, we worship God alone, but in other matters, we gladly serve you, acknowledging you as kings and rulers of men, and praying that with your kingly power, you may also be found to possess sound judgment. However, if you disregard our prayers and honest explanations, we shall not suffer any loss, since we believe (or rather, are convinced) that every person will suffer punishment in eternal fire according to the merit of their deeds and will give an account according to the power they have received from God, as Christ indicated when He said, “To whom God has given more, of them shall more be required.”

Tertullian, On Idolatry Direct teaching
...rsons set up for worship, but because of its practices, which belong to demons. The things that are Caesar's are to be given to Caesar. It is enough that He added, "and to God the things that are God's." What things, then, are Caesar's? Clearly, the things being discussed at that time, whether the poll tax should be paid to Caesar or not. So the Lord asked for the coin to be shown to Him, and asked whose image was on it. When He heard that it was Caesar's, He said, "Render to Caesar the things that are Caesar's, and to God the things that are God's." That is, give to Caesar the image of Caesar, which is on the coin, and give to God the image of God, which is on man. So give money to Caesar, but give yourself to God. Otherwise, what will belong to God, if all things belong to Caesar? Then do you say, "The lamps before my doors, and the laurels on my posts, are an honor to God"? Of course they are there, not because they honor God, but because they honor the one who is treated in God's place by ceremonies of that kind, as far as can be seen, except for the religious act itself, which in secret belongs to demons. We should be certain of this, especially for those whose notice this

Apostolic Constitutions, Apostolic Constitutions Direct teaching
... as witnesses against yourselves, and do not be judged by them. Do not owe them anything because of tribute or fear. But render to Caesar the things that are Caesar's, and to God the things that are God's, Matthew 22:21, such as tribute, taxes, or poll money, just as our Lord, by giving a piece of money, was freed from disturbance. So choose instead to suffer harm, and to pursue the things that make for peace, not only among the brothers, but also among the unbelievers. For by suffering loss in the affairs of this life, you will be sure not to suffer loss in the concerns of piety, and you will live in a godly way and according to the command of Christ. But if brothers have lawsuits with one another, which God forbid, you who are the rulers ought to learn from there that such men are not doing the work of brothers in the Lord, but rather the work of public enemies. One of the two will be found to be mild, gentle, and a child of light; but the other will be unmerciful, insolent, and covetous. Therefore, let the one who is condemned be rebuked. Let him be separated. Let him undergo the punishment for his hatred toward his brother. Afterward, when he repents, let him be received aga

Tertullian, De Fuga in Persecutione Direct teaching
...ct? So he who makes terms to have this at a price opposes the divine appointment. Since, therefore, Caesar has laid nothing on us in this way as if we were a tributary sect—in fact, such an imposition can never be made—with Antichrist now close at hand, and gaping for the blood, not the money, of Christians, how can it be pointed out to me that there is the command, "Render to Caesar the things which are Caesar's"? A soldier, whether an informer or an enemy, extorts money from me by threats, demanding nothing on Caesar's behalf. In fact, he does the very opposite when, for a bribe, he lets me go—Christian as I am, and by the laws of man a criminal. The denarius that I owe to Caesar is of another kind, something belonging to him. That was the matter in question then, since it was a tribute coin owed indeed by those subject to tribute, not by sons. Or how shall I render to God the things which are God's, namely, His own likeness and money inscribed with His name, that is, a Christian man? And what do I owe God, as I do Caesar the denarius, except the blood that His own Son shed for me? Now if I do owe God a human being and my own blood, and I now stand at a moment when payment of
