Christianity is NOT a religion; it is the proclamation of the end of religion. Religion is a human activity dedicated to the job of reconciling God to humanity and humanity to itself. The Gospel, however - the Good News of our Lord and Savior, Jesus Christ, is the astonishing announcement that God has done the whole work of reconciliation without a scrap of human assistance. It is the bizarre proclamation that religion is over - period.
