What does this mean?

Carthage, Missouri is named after the famous, ancient, north African city of Carthage, or Carthago, St. Augustine's early home. Carthage posed a very real threat to the city of Rome and its desire for world dominance. These two cities were therefore arch enemies. The Roman elder statesman Cato the Elder is said to have ended all his speeches in the senate with the phrase "Carthago delenda est" which means "Carthage must be destroyed."
Thus the title of this blog means "Carthage must NOT be destroyed!" Of course, nobody would want his own city destroyed, but my fuller meaning, being a Lutheran Pastor, is a prayer that God would continue to bless the spiritual life in this city through the preaching of the pure Gospel and the correct administration of the sacraments. It is a prayer that God would let Faith Lutheran Church of Carthage continue to be the salt-of-the-earth preservative in our community!
