What was the protestant movement that believed every word in the bible was the truth called?

Answer 1

This was the Reformation, where Protestants believed and taught what came to be known as 'sola scriptura', or 'scripture alone.' In "The Creeds of Christendom" Philip Schaff says:-

The Reformation was eminently practical in its motive and aim. It started from a question of conscience: 'How shall a sinner be justified before God?' And ... 'What shall I do to be saved?' The answer given by the Reformers ... was: 'By faith in the all-sufficient merits of Christ, as exhibited in the holy Scriptures.' And by faith they understood not a mere intellectual assent to the truth, or a blind submission to the outward authority of the Church, but a free obedience, a motion of the will, a trust of the heart, a personal attachment and unconditional surrender of the whole soul to Christ, as the only Saviour from sin and death [and] The absolute supremacy and sufficiency of Christ and his Gospel in doctrine and life, in faith and practice, is the animating principle [of] the Reformation, and the essential unity of Protestantism ...

...

The Reformers were baptized, confirmed, and educated, most of them also ordained, in the Catholic Church, and had at first no intention to leave it, but simply to purify it by the Word of God. They shrank from the idea of schism...When the Pope refused to satisfy the reasonable demand for a reformation of abuses, and hurled his anathemas on the reformers, they were driven to the necessity of organizing new churches and setting forth new confessions of faith, but they were careful to maintain and express in them their consensus with the old Catholic faith as laid down in the Apostles' Creed.
