Did you notice that the creeds were divided into 3 separate parts? They speak of creation and God’s divinity in the first part. They claim our belief in salvation and redemption from sin in the second part. Finally, they reveal the process of sanctification in the conclusion and third part. All of these coincide with the faith we profess at our baptism.
Even though many creeds have been written throughout history, all Catholic creeds contain these 3 parts, or articles. They were written at different times, and reflect each period accordingly. However, because they are true to the Revelation of Christ, they remain true to the current faith as well, since the Church Jesus instituted was founded on everlasting truth, and can never be outdated.
