What does Mark 2:15 mean?

The passage is vague regarding whose table is mentioned and who is hosting the dinner. However, Luke 5:29 is clear that Levi has invited Jesus and others for a great feast. They recline at the table, laying on their sides or bellies with their legs behind them, leaning on their left arms and eating with their right hand.

Tax collectors are easy enough to identify, but Levi also invites "sinners." This is a technical term given by the Pharisees to Jews who do not have the time or inclination to attempt to follow their excessive rules. They aren't necessarily breakers of the Mosaic Law, although undoubtedly some are. "Sinners" are also called "people of the land."

These "tax collectors and sinners" are identified in contrast with Jesus and His disciples. The ungodly Levi and his friends are dining with the Son of God and His followers. This contrast angers the devout Jewish religious leaders and other people in the community (Mark 2:16). Yet Mark notes "there were many who followed" Jesus, including people who typically would not be identified as religious. The appeal of Jesus has spread far beyond the synagogue to the "sinners" in the community who respond positively to His message.
