"Who Has Spoken Through the Prophets" or the Spirit's Voice in Holy Scripture

The bishops who formulated the Creed wanted to make sure the authority and trustworthiness of Scripture was acknowledged, and what better way than to highlight Scripture as the vehicle of prophetic words from the Holy Spirit (another way of saying the Bible is the word of God)? And although the prophets, the Apostles, and Jesus Himself had an exceedingly high view of the Bible and its divine origin, they also readily acknowledged its thoroughly human origin. This is all the more evidence of the desire God has to work in, through, and alongside His image bearers to accomplish His purposes—even in the creation of his sacred texts!
