From the Wall Street Journal's March 31, 2012 interview with Timothy Cardinal Dolan, When the Archbishop Met the President:
What about the argument that vast numbers of Catholics ignore the church's teachings about sexuality? Doesn't the church have a problem conveying its moral principles to its own flock? "Do we ever!" the archbishop replies with a hearty laugh. "I'm not afraid to admit that we have an internal catechetical challenge—a towering one—in convincing our own people of the moral beauty and coherence of what we teach. That's a biggie."
For this he faults the church leadership. "We have gotten gun-shy . . . in speaking with any amount of cogency on chastity and sexual morality." He dates this diffidence to "the mid- and late '60s, when the whole world seemed to be caving in, and where Catholics in general got the impression that what the Second Vatican Council taught, first and foremost, is that we should be chums with the world, and that the best thing the church can do is become more and more like everybody else."
