I believe that I’ve mentioned this before, but for me, the most important phrase in the Pledge of Allegiance is “under God.” The reason I place such importance on this is that:

All political power is the gift of God; but when men deify the state, either directly by a religious cult or indirectly by demanding for it the total loyalty and obedience that are due to God alone, it ceases to be human and become bestial. — G. B. Caird

We must place our nation “under God” for its own good and for ours.
