The text of today contains the second Passion and Resurrection Prediction in the Gospel of Matthew. In this one, however, it is clearer that God will deliver up the Son of Man., but it is human hands into which he will be delivered. God will also vindicate Son of Man. Since Matthew tries to avoid scenes in Mark, which speak of the disciples’ inability to understand, here too, the response of the disciples is to be “greatly distressed”.
The pericope about the “Temple Tax” (17:24-27), which follows, is exclusive to Matthew. The point being made is about freedom and concern for others. Just as the Son of Man gives his life for others and freely, so too the members of his community live lives of freedom but concern for others and not wanting to be a cause for their stumbling will result in a foregoing of that freedom.
There are times when we do things more to avoid scandal than because they are important and need to be done.
