Col Quotes
And therefore, so far as we are concerned, the followers of Pythagoras, who abstain from all things that contain life may do as they please; only observe the different reason for abstaining from things that have life on the part of the Pythagoreans and our ascetics. For the former abstain on account of the fable about the transmigration of souls, as the poet says:-"And some one, lifting up his beloved son,Will slay him after prayer; O how foolish he!”We, however, when we do abstain, do so because "we keep under our body, and bring it into subjection,” (Cf. I Co. ix. 27) and desire "to mortify our members that are upon the earth, fornication, uncleanness, inordinate affection, evil concupiscence;” (Cf. Col. iii. 5) and we use every effort to "mortify the deeds of the flesh.” (Cf. Rom viii. 13)
