The criticism that the Bible contains ethical issues arises from misinterpretations, such as incongruence in distinguishing descriptions from prescriptions, as well as disregarding the historical and cultural context. Critics often mix descriptive passages with prescriptive ones. Additionally, while God provided just laws, human implementations were occasionally flawed, reflecting human tendencies towards sin. God progressively revealed His moral standards over time, suitable to humanity's spiritual progress. Issues like slavery and gender bias, often critiqued, were regulated as per the societal conditions of different eras. The Bible's primary ethical principle is love, intended to lead humanity towards Jehovah.
