For Erasmus, it would be better for people in general to bear the disease of moralism and choice than to be cured of it by the preaching and teaching of God’s unconditional election of sinners in Christ.
When explaining that sinners were saved by grace alone Erasmus would not go so far as to say that the reception of God’s grace erased human responsibility.
Desiderius Erasmus and many humanists had for a while held out hope for Luther’s call for reform and many of the reformers were themselves, to some degree, humanists.
