Self-mortification must be moderate, monitored
VATICAN CITY -- Reacting to a report that Pope John Paul II practiced self-mortification, including flagellation, experts in spirituality said ascetical practices are part of the Christian tradition, but should be used in moderation and under the guidance of a mature spiritual director.
"Union with the redeeming suffering of Christ comes through accepting the trials and suffering of life or, like in the case of Pope John Paul II, with the voluntary choice of physical suffering," said Cardinal Georges Cottier, theologian of the papal household under the late pope.
"Spiritual masters insist this practice must always be prudent and never without a spiritual guide," because "pathological abuses are always possible," the cardinal said Feb. 4 in a written response to questions from Catholic News Service.
Cardinal Cottier said the practice of self-mortification did not conflict with what Pope John Paul wrote and preached about the beauty and sacredness of the human body and the obligation of Christians to care for their bodies.
