From Pope John Paul II on October 14, 2001:
Teachers provide instruction in the original sense of the term, that is, they make a substantial contribution to building the personality; they educate in the sense of the ancient Socratic image, helping students to discover and to make use of the skills and gifts of each one…
You have been called to teach. This is a vocation, a Christian vocation…There, at your teacher’s chair and desk, God has called you by name to an indispensable service to the truth.
