“Be not ye called Rabbi,” that ye take not to yourselves what belongs to God. And call not others Rabbi, that ye pay not to men a divine honour. For One is the Master of all, who instructs all men by nature. For if man were taught by man, all men would learn that have teachers; but seeing it is not man that teaches, but God, many are taught, but few learn. Man cannot by teaching impart an understanding to man, but that understanding which is given by God man calls forth by schooling.
