While he was guilty of many doctrinal errors (e.g., infant baptism; double-predestination; total depravity; sola scriptura; sola fide), Martin Luther correctly held to the view that baptism was salvific, not a mere symbol as Calvin and Zwingli taught. Indeed, Luther severely castigated his fellow Magisterial Reformers on this issue. Speaking of those who espoused a purely symbolic view of salvation, he wrote:
So they have become nothing but legalists and Mosaists, defecting from Christ to Moses and calling the people back from Baptism, faith and the promises of Christ to the Law and works, changing grace into the Law and the Law into grace" (Luther's Works, vol. 26 p. 143)
