In Paul's first letter to the church in Corinth, he argues that the Exodus event reveals something about what it means to be a member of the church. In the Exodus event, the Hebrew people are transformed into the nation of Israel - God's chosen people. And in Baptism, people of all kinds are transformed into children of God - members of God's family. In the wilderness, Israel ate manna and today we commune with the same heavenly food and drink. Now, as then, we must learn to coexist with our new family members despite the challenge.
