XII. (40) But as after Cain had begotten Enoch, one of the posterity of Seth is also subsequently called Enoch, it may be well to consider, whether the two namesakes were men of different or of similar dispositions and characters. And at the same time that we examine this question let us also investigate the differences between other persons bearing the same name. For as Enoch was, so also Methusaleh and Lamech were both descendants of Cain, and they were no less the descendants of Seth also. (41) We must therefore be aware that each of the aforesaid names, being interpreted, has a double signification; for Enoch, being interpreted, means, as I have already said, “thy grace,” and Methusaleh means, the sending forth of death. Lamech, again means, humiliation. Now the expression, “Thy grace,” is by some persons referred to the mind that is in us; and by more learned and sounder interpreters it is referred to the mind of other persons. (42) They therefore who say that all thinking, and feeling, and speaking, are the free gifts of their own soul, utter an impious and ungodly opinion, and deserve to be classed among the race of Cain, who, though he was not able to master himself, yet dared to assert that he had absolute possession of all other things; but as for those persons who do not claim all the things in creation as their own, but who ascribe them to the divine grace, being men really noble and sprung out of those who were rich long ago, but of those who love virtue and piety, they may be classed under Seth as the author of their race. (43) The race of these men is difficult to trace, since they show a life of plotting, and cunning, and wickedness, and dissoluteness, full of passion and wickednesses, as such a life must be. For all those whom God, since they pleased him well, has caused to quit their original abode, and has transformed from the race of perishable beings to that of immortals, are no longer found among the common multitude.
