What or whom did john wycliffe argue was the highest source of religious authority?

John Wycliffe argued that the Bible was the highest source of religious authority.

Explanation:

John Wycliffe was an English church reformer. As a professor of theology at Oxford University, he wanted to reduce philosophy to the Bible and the Church Fathers.

He is especially remembered as the reformer who stated that people could confess their faith without the intervention of priests, using the Bible as a guideline. Nor were priests needed to forgive sins.

He distinguished between the eternal church and its earthly form. According to him, the earthly church should not have any property. It had to return the goods it owned to the original owners. This provided Wycliffe with much support from the English nobility.

He also contested the Pope's claim that he had all worldly power and that the princes were subordinate to him. For him, the pope was the personification of anti-christ. Just like later Martin Luther, he also sharply criticized the indulgence trade.
