A new wave of research on religious leadership is finding significant numbers of clergy show evidence of struggling with clinical signs of narcissism. Yet there is a powerful countervailing force: Humility.

Pope Francis, the first Latin American pontiff, was charged in his own way with opening the windows of the Catholic Church to the modern world with his election in 2013.

Human beings may be hard-wired since evolution to separate into tribes in response to fear and uncertainty. But science also shows we are capable of working together for the common good when we leave our tribal cocoons and get to know our neighbors in ways that promote understanding. It starts with listening to one another.

In a series of scientific advances, researchers are developing a body of evidence challenging old stereotypes of humility as the province of weak-willed, stoop-shouldered individuals of low self-worth. The reality, research shows, is that it takes a strong will and courage to celebrate the gifts of others, while being honest about one’s own shortcomings. But it pays off. Just as a lack of humility can lead to a downward spiral of suspicion, distrust and violence, so, too, can the practice of humility reinforce other virtues and contribute to a more generous, inclusive, caring society.

As he marks his third anniversary on the job, Pope Francis is providing encouragement, renewed optimism and a new energy to many of the world’s 1.2 billion Catholics. It is an appeal that extends beyond Catholics as the humble leader addresses issues from the refugee crisis to the environment. But can one person, even someone as charismatic as Francis, bring about lasting change?
