ANSWER: Uncleanness is that which we think or do that has its source in a spirit rebellious to God. Words with similar meanings include filthy, evil and impure! Inordinate affection means unnatural passions of the flesh. This may include passions for sodomy, bestiality and other unlawful sexual activity. Evil concupiscence means evil desires and is similar to inordinate affections, but is used in a broader sense to include a deep longing and yearning for the unnatural and sinful activities of the flesh.
