" Christians have seldom been less appealing than when acting in the name of “Christendom.” But when the faithful have ignored political power, they have sometimes again brought discredit on their ideals. Sins of omission can be as deadly as sins of commission. So the exercise of politics requires walking a tightrope. It is both a temptation and a responsibility; it can act like an addictive drug or a healing medicine. "
