VERY interesting.
I found that interesting, too.
In August 2001 I attended an orientation at my church, as I was going to be teaching catechism that school year. At the Mass that started off our day, our pastor gave a startling homily.
He spoke of the important role catechists have always played since the very beginning of the Church. He reminded us that many many martyrs of the early Church were catechists. He then said (paraphrase) "And that time will come again. As sure as I'm standing here, catechists will be again be punished for spreading the Word of the Lord."
I thought of his words a few weeks later, and have often pondered them since.
