Our bishops," says Father Frans Haarsma, professor of pastoral psychology at the Catholic niversity of Nijmegen, "made their fatal mistake at the time of the upheaval about the Dutch catechism. Cardinal Alfrink then minimized the objections of the Vatican as not being serious, a matter of minor corrections. Instead, he should have put his foot down and used the occasion to affirm the legitimacy of difference in theological viewpoints, while at the same time asserting the fundamental commitment of the Dutch Church to its unity with Rome. Pluriformity implies that one dares uphold the legitimacy of differentiation in theological viewpoints and that there are limits to Roman authority."
