The use of statements of faith among Christians started in the first century. Noted among these was the statement of belief that was issued by the church counsel at Jerusaleum. This counsel was held over the subject of how much of the Old Testament law was to be held accountable to by gentiles. This according to Acts 15 was a hotly considered subject. If you read through this passage the whole argument was answered by James in verse 20. This was a doctrinal statement as to practice among believers.
"And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved. When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question. And being brought on their way by the church, they passed through Phenice and Samaria, declaring the conversion of the Gentiles: and they caused great joy unto all the brethren. And when they were come to Jerusalem, they were received of the church, and of the apostles and elders, and they declared all things that God had done with them. But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses. And the apostles and elders came together for to consider of this matter. And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe. And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us; And put no difference between us and them, purifying their hearts by faith. Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear? But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they. Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles and wonders God had wrought among the Gentiles by them. And after they had held their peace, James answered, saying, Men and brethren, hearken unto me: Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name. And to this agree the words of the prophets; as it is written, After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up: That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things. Known unto God are all his works from the beginning of the world. Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God: But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood."
(Act 15:1-20)
Then there was the doctrinal statement that gave rise to many of the confessions of the early church. This is one of the most important confessions of the early church and it is found in the book of I Corinthians.
"Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: And that he was seen of Cephas, then of the twelve: After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time".
(1Co 15:1-8)
Charles Spurgeon had this to say about a Baptist Cathecism:
I am persuaded that the use of a good Catechism in all our families will be a great safeguard against the increasing errors of the times, and therefore I have compiled this little manual from the Westminster Assembly's and Baptist Catechisms, for the use of my own church and congregation. Those who use it in their families or classes must labour to explain the sense; but the words should be carefully learned by heart, for they will be understood better as years pass.―C. H. Spurgeon
Another baptist preacher and educator of the later part of the 19th century and the first part of the 20th century had this to say:
"There never was a man in the world without a creed. What is a creed? A creed is what you believe. What is a confession? It is a declaration of what you believe. That declaration may be oral or it may be committed to writing, but the creed is there either expressed or implied."―B.H. Carroll
