"The Archbishop himself explained to us why the Church has such powers, and why it strives to keep the education of children in the hands of the clergy. He knows how important it is to impart religious instruction to young people, who are incapable of forming a reasoned judgment on the subject in which they are instructed, and who take on trust the teaching of their elders. The clergy know very well what is the result of ramming into the heads of children from seven years old upwards the ideas for which (Archbishop) Cieplak stands; by this means they catch them fast from tender years in tentacles of religion,"
