"Lutherans, whose arguments and mistakes will not be difficult to contest or discover, do not want to attribute any value to works, and they do not understand enough the scope of the justification"

This quote by Michael Servetus is referring to the beliefs of Lutherans, a Protestant denomination of Christianity. Servetus is suggesting that Lutherans do not understand the complete scope of validation, which is the belief that an individual can be made right with God through faith in Jesus Christ. He implies that their arguments and errors are simple to identify and object to, recommending that their beliefs are not well-founded. Servetus is likely slamming Lutherans for not attributing any value to works, which is a belief that kind deeds are essential for salvation. He is recommending that Lutherans do not comprehend the full scope of reason, which is the belief that an individual can be made right with God through faith in Jesus Christ and not simply through greats. This quote is a tip that faith in Jesus Christ is the only way to be conserved which greats are not needed for redemption.
