Illuminations of readings for Sunday, Sept. 16, 2012.

First Reading: Isaiah 50:4-9a
What could be more important to a community than its teachers, whose words shape our growth and understanding? The Israelites understood this teacher, Isaiah’s so-called “Suffering Servant,” to represent their nation in exile. Christians later found in this suffering servant an image of Christ, who endures opposition, turns the other cheek, and keeps on teaching until we hear.

Psalm 116:1-8
The Psalmist today expresses joy because God has listened to his prayer, made in grief and desperation, and has brought relief from distress and anguish, and the hope of new life. His troubled soul can rest now. God has dealt bountifully in restoring life, and this gift inspires a hymn hailing God in the boldest language we find in Psalms: “I love the Lord.”

Second Reading: James 3:1-12
I hate you! Angry words can spill out of us suddenly, before we have time to think about them. And then how we wish we could take back the hurtful things we said! James reminds us in a series of colorful metaphors that words have power. Echoing the Isaiah reading, he warns us that teachers bear a heavy responsibility to use words wisely. It’s up to us to use them well.

Gospel: Mark 8:27-38
“Who do you say that I am?” Can you picture Jesus, sitting with the apostles and confronting them with this reality check? When Peter, declaring Jesus his Messiah, objects to Jesus’s warning of his coming passion and death, Jesus calls him “Satan!” We see no smiling Jesus hugging children and lambs today, but a challenge: Take up your cross and follow. If you want to save your life in the Kingdom of Heaven, be prepared to lose it now for the Gospel and Jesus’ sake.
