"When we do abstain [from eating meat], we do so because we keep under our body and bring it into subjection (I Corinthians 9:27), and desire to mortify our members that are upon the earth, fornication, uncleanness, inordinate affection, evil concupiscence (Colossians 3:5); and we use every effort to mortify the deeds of the flesh (Romans 8:13)."
