In today’s first reading, Wisdom invites everyone to her house. Even the ignorant and foolish are promised that they can become wise, if they sit down and eat with her. Paul, too, urges the Christians living in Ephesus to live sober, sensible lives, like intelligent people. But in the Gospel, Jesus confronts his disciples with a teaching that seems to fly in the face of common sense. They must eat his flesh and drink his blood, in order to have eternal life. Many of his disciples rejected this idea, and gave up following him. It’s a teaching that is incomprehensible, if we think in worldly terms. Only our faith tells us that the Body and Blood of Christ which we receive in the Eucharist is God’s promise of everlasting life.
