Now, since people tend to prize knowledge above holiness, we must be warned that this enlightening is not an understanding of the Divine Mysteries. It is a call (vocation) to obedience; and it is a mission (apostolate) to love the laws of God: the two Great Commandments. (Conversio by John Meehan 1976)
I think it is true - people love to know things - and we sometimes think because we have all this knowledge, that we are holy. (I know the commandments; I know the catechism; I know the proper rubrics for the Mass; .... etc.) But probably most of us will realize this is false if we think about it.
Oremus pro invicem!
