The true Christian was intended by Christ to prove all things by the Word of God: all churches, all ministers, all teaching, all preaching, all doctrines, all sermons, all writings, all opinions, all practices. These are his marching orders. Prove all by the Word of God; measure all by the measure of the Bible; compare all with the standard of the Bible; weigh all in the balances of the Bible; examine all by the light of the Bible; test all in the crucible of the Bible. That which cannot abide the fire of the Bible, reject, refuse, repudiate, and cast away. This is the flag which he nailed to the mast. May it never be lowered!
—John Wycliffe (c. 1320s – 31 December 1384, English scholastic philosopher, theologian, biblical translator, reformer, minister, and professor at the University of Oxford. He was an influential dissident within the Roman Catholic priesthood and is considered an important predecessor to Protestantism. Wycliffe attacked the privileged status of the clergy, which had bolstered their powerful role in England. He then attacked the luxury and pomp of local parishes and their ceremonies. Wycliffe also advocated translation of the Bible into the common language).
