Early Christian Beliefs About Augustus Caesar
Early Christian writings treat Augustus Caesar mostly as the emperor in whose reign Jesus was born. Justin Martyr, Clement of Alexandria, Tatian, Origen, Hippolytus, Tertullian, Archelaus, and Theophilus all use Augustus as a historical marker for Christ’s birth or the start of Christian history. Luke 2:1 gives the clearest Bible passage, naming Caesar Augustus in the census at Jesus’ birth. The evidence is broad for dating and history, but thin for any direct theological teaching about Augustus himself.

What did early Christians believe about augustus Caesar?
Early Christian writings treat Augustus mainly as the Roman ruler in whose reign Jesus was born, not as a figure of Christian devotion. Justin Martyr, Clement of Alexandria, Tatian, Origen, Hippolytus, Tertullian, Archelaus, and Theophilus all place Christ’s birth or the start of his public life in the reign of Augustus, and several also give Augustus’ reign length in their time lines. The strongest and most direct material is historical and biblical:
Luke 2:1 names Caesar Augustus in the census at Jesus’ birth, while Luke 3:1 and related Christian writers use Augustus as a dating marker. The evidence is broad across the second and third centuries, but it is mostly indirect for the topic itself, since these writers are usually discussing Christ’s birth, Roman history, tribute, or persecution rather than Augustus’ person or character. Some texts even use Augustus as a symbol of imperial power, but that is secondary to the main historical use.

Luke 2:1 Direct teaching
In those days a decree went out from Caesar Augustus that all the world should be registered.
-
Tatian, The Diatessaron Direct teaching
In those days, a decree went out from Augustus Caesar that all the people under his rule should be registered. This first registration took place while Quirinius was governor of Syria. And every man went to be registered in his own city. Joseph also went up from Nazareth, a city of Galilee, to Judea, to the city of David called Bethlehem, because he was from the house and tribe of David. He went with Mary, his betrothed, who was pregnant, to be registered there. While she was there, the time came for her to give birth. And she gave birth to her firstborn son. She wrapped him in swaddling cloths and laid him in a manger, because there was no place for them where they were staying.

Clement of Alexandria, The Stromata (Miscellanies) Direct teaching
...d was born in the twenty-eighth year, when the census was first ordered to be taken in the reign of Augustus. And to prove that this is true, it is written in the Gospel by Luke as follows: “In the fifteenth year of the reign of Tiberius Caesar, the word of the Lord came to John, the son of Zacharias.” And again in the same book: “And Jesus was coming to His baptism, being about thirty years old,” and so on. And it was necessary for Him to preach for only one year. This also is written: “He has sent Me to proclaim the acceptable year of the Lord.” Both the prophet and the Gospel spoke this. Accordingly, in the fifteen years of Tiberius and the fifteen years of Augustus, the thirty years were completed until the time He suffered. And from the time that He suffered to the destruction of Jerusalem are forty-two years and three months. And from the destruction of Jerusalem to the death of Commodus are one hundred twenty-eight years, ten months, and three days. Therefore, from the birth of Christ to the death of Commodus there are, in all, one hundred ninety-four years, one month, and thirteen days. And there are some who have determined not only the year of our Lord’s birth, but als

...the veil. For up to the time of Herod, they seemed to keep a kingdom in some form. And it was under Augustus that the first enrollment took place among them, and that they began to pay tribute and to be assessed. It was also from the time when our Lord Jesus Christ began to be prophesied of and looked for that princes from Judah and leaders of the people began to appear. And these, in turn, failed just as His coming drew near. If the veil that is put on in that reading of theirs is taken away, they will understand the true virtue of circumcision. They will also discover that the generation of Him whom we preach, and His cross, and all the things that have happened in the history of our Lord, are those very matters that had been predicted of that Prophet. And I could indeed wish to examine every passage of Scripture by itself, and to point out its meaning, as it should be understood. But since another subject is urgent now, we will discuss these passages at some time of leisure. For the present, what I have already said may be enough to show that it is not without reason that the veil is said to be put upon the heart of certain persons in the reading of the Old Testament. But tho

...ot punish us severely if we have failed to do Your works. For why, when You promised under Tiberius Caesar to send the Paraclete to convict us of sin and of righteousness, did You send Him only under Probus the Roman emperor, and leave us orphaned, even though You said, 'I will not leave you comfortless,' or 'orphaned,' and after You had also assured us that You would send the Paraclete soon after Your departure? What could we orphans do, having no guardian? We have committed no fault. It is You who have deceived us." But let such an idea be far from us in the case of our Lord Jesus Christ, the Savior of every soul. For He did not limit Himself to mere promises. But when He had once said, "I go to my Father, and I send the Paraclete to you," He immediately sent that gift of the Paraclete, dividing it and imparting it to His disciples, though bestowing it in greater fullness upon Paul.
