Credibility is absolutely essential to viable leadership, whether in religion, politics, or business. A leader who undercuts one of his or her promises effectively expunges it of any worth and is essentially a “lame-duck” leader thereafter unless he or she puts difficult effort into becoming worthy of being trusted again. It does not take long for followers to get the message if one of them who relied on the promise is punished for doing so. Chairman Mao is infamous for having made such a promise in the Hundred Flowers movement. Unfortunately, he killed many Chinese who relied on Mao’s word.

Fortunately for the Catholic pope, his own religion offers him a way out.
