In today's Gospel reading from Luke 17, Jesus said to his disciples, "Things that cause sin will inevitably occur, but woe to the one through whom they occur." Two observations. First, sin separates us from God, so anything that tends to distance us from God cannot have come from him. We must do our utmost to remain in union with God. Secondly, we must never cause anyone to sin. Therefore, our example as a disciple of the Lord must be perfect. Again, union with him should take care of that.
