I think Pope Benedict XVI expressed very well this point about teaching and education that I have been exploring in recent posts. Here are some words he preached two years ago. I would say further that his entire service as successor of St. Peter was a continual witness to what he said here:
The true educator does not bind people to himself, he is not possessive. He wants the child, or the disciple, to learn to know the truth and establish a personal relationship with it. The educator does his duty to the end, he does not withdraw his attentive and faithful presence; but his objective is that the learner hears the voice of the truth speak to his heart and follows it on a personal journey.
