Martin Luther - He complained that the pope was the main mediatopr of God’s will rather than the book of scriptures, and that he nailed to the entryway of the Wittenberg church; the act that begun the Reformation.
John Calvin - Calvin complains that rather than instructing and pursuing holiness, the authority within the Roman church exercises “a most brutal tyranny” over the souls of the individuals of God, claiming powers and authority not given to them by God.
Please correct any mistakes in my answer!! I'd be happy to fix it!! :)
