Jesus’ practice of table fellowship and his teaching concerning issues related to table fellowship contravened the understanding of Israel as a holy, separated community. In this context, table-fellowship cannot be described simply as festive celebration and acceptance, but as a political act of national significance: to advocate and practice a different form of table fellowship was to protest against the present structures of Israel. Moreover, there was more than protest – an alternative program was advocated for the people of God in their historical existence.
A significant part of the reason Jesus was crucified, is for these kinds of acts. They may look innocent to us, but because they are a part of Jesus' larger mission, they must be seen in relationship to one another.
