Why did john Knox disapprove or object the catholic church?

John Knox disapproved of the Catholic Church primarily due to its perceived corruption and the authority of the Pope, which he believed undermined the true teachings of Christianity. As a key figure in the Protestant Reformation, Knox advocated for a return to biblical principles and criticized the Church’s practices, such as the veneration of saints and the sale of indulgences. His strong belief in predestination and the sovereignty of God further fueled his opposition to Catholic doctrines. Ultimately, Knox sought to establish a reformed church that emphasized individual faith and direct access to Scripture.
