Gospel according to Saint Mark 2,13-17
When Jesus went out again beside the lake, a crowd came to Him and He taught them. As he walked along, he saw a tax collector sitting in his office. This was Levi, the son of Alpheus. Jesus said to him, «Follow me». And Levi got up and followed Him. And it so happened that while Jesus was eating in Levi’s house, tax collectors and sinners were sitting with Him and His disciples for there were indeed many of them. But there were also teachers of the Law of the Pharisees’ party, among those who followed Jesus, and when they saw Him eating with sinners and tax collectors, they said to his disciples, «Why! He eats with tax collectors and sinners!». Jesus heard them and answered, «Healthy people don’t need a doctor, but sick people do. I did not come to call the righteous but sinners».
