27 Humility in the spirit of the Gospel and prayer for the assistance of grace are perfectly compatible with self-confidence and heroism. The Church of Christ, which throughout the ages and to the present day numbers more confessors and voluntary martyrs than any other moral collectivity, needs lessons from no one in heroism of feeling and action. The odious pride of reformers only covers itself with ridicule when it rails at Christian humility as though it were but a cowardly pose of self-degradation.
