ran across this post @ U2sermons. apparently a united methodist lay leader did a cd for his pastor that used u2 songs according to the book on social principles. here's the list but follow the link for the discussion of the list.
Sunday Bloody Sunday
North and South of the River
Peace on Earth
Walk On
Where the Streets Have No Name
In God's Country
Crumbs from Your Table
Mothers of the Disappeared
Miracle Drug
One Step Closer
When I Look at the World
If God will Send His Angels
Drowning Man
When Love Comes to Town
Pride
Yahweh
on a side note: why is our book on social principles so small compared the our book on book of discipline?
