115 But those mysteries pertain not to individuals only, but to the whole human race. For observe the order of grace according to the type of the Law. When the first trumpet sounds, it collects those towards the east, as the chief and elect; when the second sounds, those nearly equal in merit, who, being placed towards Libanus, have abandoned the follies of the nations; when the third, those who as it were, tossed on the sea of this world, have been driven here and there by the waves of this life; when the fourth, those who have by no means been able sufficiently to soften the hardness of their hearts by the commandments of spiritual utterance, and therefore are said to be towards the north— for, according to Solomon, the north is a hard wind.
