Final answer:
The New Testament arose from a complex process with early Christians documenting teachings they believed to be a fulfillment of the Old Testament, with the canonical texts being solidified over time. The embrace of Scripture Alone during the Protestant Reformation was facilitated by the printing press, allowing direct access to the Bible.
Step-by-step explanation:
The development of the New Testament was not an outcome of an authoritative 'church of power' but instead was the culmination of a process involving early Christians from various backgrounds, including both Jews and pagans, who were seeking to document the life and teachings of Jesus Christ and the fulfillment of Old Testament prophecies. The process of establishing a canonical set of texts for Christianity took hundreds of years and included extensive debates and disagreements among Christians about the true message of Christ's teachings. It wasn't until the printing press was invented and the Bible translated into vernacular languages that individuals could directly access the scriptures, leading to various interpretations and eventually, the Protestant Reformation, which emphasized Scripture Alone as the basis of faith apart from the teachings of the Church.
