I have not come to call the righteous

But for what reason do the Pharisees blame the Savior, Jesus, for eating with sinners? Because it was the law to put a distinction between the holy and the profane: that is, that whatever was hallowed was not to be brought into contact with things profane.

They made the accusation therefore supposedly vindicating the law; but really it was envy against the Lord, and readiness to find fault. But He shows them that He is present now, not as a judge, but as a physician; and He performs the proper duty of the physician’s office, in being in the company of those in need of healing.

But no sooner had they received an explanation of their first accusation, than they bring forward another, finding fault because His disciples did not fast, wishing to obtain hereby an opportunity against Him.
