"The following counsel of prudence may be recommended to all Catholics: 'Cultivate the habit of thinking that if the Church teaches it as a matter of faith or morals then somewhere there is a good case for it drawn from revelation, tradition or natural reason.' This may seem utterly obvious, but there are many who would regard what I say as intellectually naive and as encouraging an attitude of docility. Well, the more I pursue questions of doctrine, the more I am impressed by the richness of the Church's resources, and so far as docility is concerned, it is a virtue whose corresponding vice is ineducability. Better to be teachable than not."
