What does Cranach's woodcut suggest about protestants who had a different interpretation than Luther's about the lord's supper?

Cranach's woodcut, "The Last Supper," suggests that Protestants who had a different interpretation than Luther's about the Lord's Supper were seen as deviating from the established beliefs and teachings of the movement. It may have conveyed a sense of division and the importance of adhering to Luther's interpretation as a unifying principle within the Protestant community.
