Medieval Latin Christians understood Muhammad as a corrective prophet completing earlier revelations

Evidence

Salah ad Din’s letter to the Emperor, often quoted by his Latin contemporaries, enshrined the succinct formula, “Our instructor and God’s Apostle, Muhammad, whom He sent for the correction of the right religion: may He make it appear above all religions.’ James of Vitry realised that Muhammad’s mission was to ‘expound to the world and declare’ the revelations given to Moses and Christ, and to “correct and instruct those who ill understood the commands of religion’. — Norman Daniel, Islam and the West, 141
