It’s a reality: not everybody raised in the Church stays in the Church. That may convict the strays, but leaders do not escape scrutiny:
h) We recognize that some Catholics have occasionally strayed from the Gospel, which requires a way of life more faithful to truth and charity, more simple, austere, and in solidarity, while we too have lacked the courage, persistence, and docility to grace to follow the renewal begun by Vatican II, faithful to the perennial Church, under the impulse of the previous General Conferences, and to affirm the Latin American and Caribbean face of our Church. We acknowledge that we are a community of poor sinners, imploring God’s mercy, gathered, reconciled, united, and sent forth by the power of the resurrection of his Son and the grace of conversion of the Holy Spirit.
The bishops are correct to say that the more demanding aspects of the Second Vatican Council require “courage, persistence, and docility to grace.” Courage often involves an interior disposition. Or more accurately, a change in position. I note many of my North American brothers and sisters get concerned, at times hyper-concerned about relatively small points of philosophy like organic change. Sometimes in doing so they miss the matters of greater import. Mainly conversion. Conversion, both the initial and continuing varieties, require courage to go where we have not been, and to change–sometimes not without rupture–the way we’ve thought, acted, and preached.
