I've been told that I am obviously not a Christian because I watch movies. Because I believe women can be pastors. Because I don't take Mass in a Catholic church. Because I've read Brian McLaren and N.T. Wright. Because I voted for Obama. Because I am not a Calvinist.
If you read only one book about the Sabbath, it should be Abraham Joshua Heschel's 1951 classic
