3. Augustine answered: I acknowledge the apostolic greeting. You see who you are that employ it, but see from what source you have learned what you say. For in these terms Paul salutes the Romans, and in the same terms the Corinthians, the Galatians, the Ephesians, the Colossians, the Philippians, the Thessalonians. What madness is it, therefore, to be unwilling to share the salvation of peace with those very Churches in whose epistles you learned its form of salutation?
