Some ignorant clerics reject calculations of this kind (for shame!) and do not wish to keep their phylacteries, that is, they do not preserve the order, which they have received in the bosom of mother church, nor do they persist in the holy teaching of meditation. They should consider carefully the way of the Pharisees and the Sadducees, and they should spit out their doctrine like filth. A cleric ought to be the keeper of his own soul, just as a noble man subjects a young foal to the yoke, so he ought to subject his own soul to service, by filling the alabaster box with precious oil, that is, he ought to be inwardly subjected daily, by obeying the divine laws and admonitions of the Redeemer.[36]
