Early Creeds and the Rule of Faith
Early Christian writings treat the rule of faith as a fixed summary of apostolic teaching that guards the church from false doctrine. Tertullian, Irenaeus, Novatian, Victorinus, Gregory Thaumaturgus, and Cyprian all use this idea to define true Christian belief. Bible passages like Jude 1:3 and 2 Timothy 1:13 fit this same pattern of a delivered faith and sound words.

What did early Christians believe about early Creeds and the Rule of Faith?
Early Christian writers treated the rule of faith and the apostolic tradition as a fixed standard for Christian belief, not a private opinion. Tertullian, Novatian, Victorinus, Gregory Thaumaturgus, Irenaeus, Cyprian, Clement of Alexandria, and Origen all speak of a received rule, creed, or tradition that guards true teaching and rejects false doctrine.
The evidence is broad across the 2nd and 3rd centuries, and it includes both teaching on the rule itself and how churches used it to test doctrine, baptism, and unity. Some excerpts are shorter or more general than others, but the overall pattern is clear and consistent. Bible passages such as Jude 1:3, 2 Timothy 1:13, Titus 1:9, and 2 Thessalonians 2:15 give strong background for this early Christian emphasis on a delivered faith and sound words.

... is a short way for religious and simple minds both to put away error and to find and bring out the truth. For if we return to the head and source of divine tradition, human error ceases. And when the reason of the heavenly sacraments has been seen, whatever lay hidden in obscurity under the gloom and cloud of darkness is opened into the light of truth. If a channel supplying water, which once flowed plentifully and freely, suddenly fails, do we not go to the fountain so that the reason for the failure may be found there? We ask whether the water has failed at the source because the springs have dried up, or whether, after flowing from there free and full, it has failed in the middle of its course. Then, if this has happened because of the fault of a broken or leaking channel, so that the steady stream does not flow without interruption and continuously, the channel is repaired and strengthened, and the collected water can be supplied for the use and drinking of the city with the same richness and abundance with which it comes from the spring. And this is what the priests of God ought to do now, if they would keep the divine precepts: if the truth has wavered or faltered in any

Did early Christians use a creed in baptism and confession?
The compiled sources show that confession of the faith was tied to baptism and to the Church's public profession. Gregory calls the Church's confession a creed, and Tertullian says Christians made profession of the faith in the words of its rule when entering the water.

But the Church’s confession, and the creed that brings salvation to the world, is the one that speaks about the incarnation of the Word. It testifies that He gave Himself to the human flesh He received from Mary, while still preserving His own identity and undergoing no divine transfer or change. Instead, He was joined to the flesh in the likeness of man, so that the flesh was made one with the divinity, because the divinity had taken on the capacity to receive the flesh in the fulfillment of the mystery. And after death was dissolved, there remained in the holy flesh a lasting impassibility and an unchanging immortality. Man’s original glory was taken up into it again by the power of the divinity, and then was given to all men through the appropriation of faith.

Irenaeus, Against Heresies: Book III Direct teaching
...t He, the Father of our Lord Jesus Christ, was preached by the Churches and may also understand the apostolic tradition of the Church. This Epistle predates those who now spread falsehoods and invent another god beyond the Creator and Maker of all things. Clement was succeeded by Evaristus, followed by Alexander; then, sixth from the apostles, Sixtus was appointed; after him, Telesphorus, who was gloriously martyred; followed by Hyginus, then Pius, and then Anicetus. Soter succeeded Anicetus, and now, in the twelfth place from the apostles, Eleutherius holds the office of the episcopate. Through this order and succession, the ecclesiastical tradition from the apostles and the preaching of the truth have come down to us. This is ample proof that there is one and the same life-giving faith, preserved in the Church from the apostles until now, and handed down in truth.

All the Asian Churches testify to this, as do the successors of Polycarp to this day—a man of far greater significance and a more steadfast witness of truth than Valentinus, Marcion, and the other heretics. He was the one who, coming to Rome during the time of Anicetus, led many away from these heretics to the Church of God, declaring that he received this singular truth from the apostles—that which is transmitted by the Church. Some heard him recount that John, the disciple of the Lord, went to bathe at Ephesus, and upon seeing Cerinthus inside, rushed out without bathing, shouting, "Let us flee, lest the bath-house collapse, because Cerinthus, the enemy of truth, is inside." Polycarp himself also replied to Marcion, who once encountered him and asked, "Do you know me?" “I do know you, the firstborn of Satan.” This illustrates the disdain the apostles and their disciples held against even speaking with anyone who corrupted the truth; as Paul also says, “A heretic, after the first and second warning, reject; knowing that such a person is warped and sins, condemned by himsel

...roclamation, calls him who is willing, and crowns him who is able to continue unmoved as far as the truth is concerned. And in truth, the Word does not wish him who has believed to be idle. For He says, "Seek, and you shall find." Matthew 7:7. But seeking ends in finding. It drives out empty trifling, and approves the contemplation that confirms our faith. And this I say, "lest any man beguile you with enticing words," Colossians 2:4, says the apostle, evidently as having learned to distinguish what was said by him, and as being taught to meet objections. "As you have therefore received Christ Jesus the Lord, so walk in Him, rooted and built up in Him, and established in the faith." Colossians 2:6-7. Now persuasion is the means of being established in the faith. Beware lest any man spoil you of faith in Christ by philosophy and vain deceit, which does away with providence, after the tradition of men. For the philosophy that is in accordance with divine tradition establishes and confirms providence. If providence is done away with, the divine arrangement of the Savior appears a myth, while we are influenced after the elements of the world, and not after Christ. Colossians 2:8. Fo

...anged," he says, "let nothing be maintained except what has been handed down." From where does that tradition come? Does it come down from the authority of the Lord and of the Gospel, or does it come from the commands and letters of the apostles? For God bears witness and warns that the things written must be done, saying to Joshua the son of Nun, "This Book of the Law shall not depart out of your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it" Joshua 1:8. Also, when the Lord sent His apostles, He commanded that the nations should be baptized and taught to observe all things that He commanded. If, therefore, it is either ordered in the Gospel, or contained in the letters or Acts of the Apostles, that those who come from any heresy should not be baptized, but should only have hands laid on them for repentance, then let this divine and holy tradition be observed. But if heretics everywhere are called nothing other than adversaries and antichrists, if they are declared to be people who must be avoided, and to be perverted and self-condemned, why then should they not be considered worthy to be condemned by u

Was the rule of faith used to reject heresy?
Several writers use the rule of faith to separate the churches from heretical teaching and to mark out apostolic communion. Tertullian and Irenaeus especially use it to show that false teachers differ from the churches' received doctrine.

...t belong especially to themselves, but that are contrary in some points to our rule and standard of faith. At other times, they defend ideas that are especially their own by using arguments that both sides admit are valid, and that sometimes even fit with our system of belief. In this way, the truth has almost been shut out by the philosophers through the poisons with which they have infected it. Therefore, if we consider both kinds of mixing that I have just mentioned, and both are equally hostile to the truth, we see the urgent need to do two things. First, we must free the ideas that we hold in common with them from the philosophers' arguments. Second, we must separate the arguments that both sides use from the philosophers' own opinions. And we can do this by bringing every question back to God's inspired standard, except in simple cases that are free from the confusion of preconceived notions, where one may fairly accept mere human testimony. For sometimes we must borrow plain evidence of that kind even from opponents, when our opponents have nothing to gain from it. Now I am not unaware of how great a mass of writing the philosophers have gathered on this subject in their

But in vain they worship me, teaching the doctrines and commandments of men." Isaiah 29:13 Also, the Lord in the Gospel, in the same way rebuking and reproving, declares and says, "You reject the commandment of God, that you may keep your own tradition." Mark 7:13 Remembering this command, the blessed Apostle Paul also warns and instructs us, saying, "If any man teaches otherwise, and does not agree with the sound words of our Lord Jesus Christ and with His doctrine, he is proud, knowing nothing."
