Küng believes that religion's prospects depend on an ability to confront honestly its vulnerability to perversion and distortion, which often leads to the legitimation of violence. Is this a realistic hope? Can it be achieved through the unsentimental, rational scrutiny of historical traditions, through ecumenical dialogue, or through declarations? These actions may not be enough, but Küng would say that the prospect is bleak without them. Notwithstanding religion's shortcomings, Küng believes that it has virtues compared to the religionless life: it is nonelitist and broadly accessible, it speaks symbolically and emotionally as well as rationally, and it possesses continuity through its traditions. It addresses questions of origin and destiny, provides strength and security, and gives voice to an "unquenchable longing for a better world."
It would also be interesting to know more about how Küng aligns his priestly vocation, his beliefs, and the contemporary Roman Catholic Church. He spends little time in this book on the details of his long-standing differences with the Catholic Church hierarchy—all well-documented in his autobiographies. Here he summarizes his opposition in simple terms: "My criticism of the church in particular comes most deeply from suffering over the discrepancy between what this historical Jesus was, what he preached, lived out, fought for and suffered for, and what is today represented by the institutional church and its hierarchy." His loyalty to the Catholic Church comes through clearly, but it would have been intriguing to glimpse more fully how that loyalty has endured decades of controversy.
What I Believe is personal without being idiosyncratic, reasoned but not rationalized, judicious though not ponderous. Behind it lies decades of study and reflection, and they lend weight, unobtrusively for the most part, to what Küng has to say. Though one may not share some, or even many, of its author's interpretations, choices, or commitments, What I Believe remains an engaging, often eloquent, portrait of personal belief.
