"In accord with the knowledge, competence, and preeminence which they possess, [lay people] have the right and even at times a duty to manifest to the sacred pastors their opinion on matters which pertain to the good of the Church, and they have a right to make their opinion known to the other Christian faithful, with due regard to the integrity of faith and morals and reverence toward their pastors, and with consideration for the common good and the dignity of persons."443
