Members of the congregation of Jehovah's Witnesses are sometimes referred to as modern-day Arians, usually by their opponents.However, the Witnesses differ from Arians by saying that the Son can fully know the Father (something Arius himself denied), and by their denial of literal personality to the Holy Spirit (Arius considered the Holy Spirit to be a person or a high angel, whereas the Witnesses consider the Holy Spirit to be God's divine breath or active force). Arians generally worshipped and prayed to Jesus as God, while the Witnesses, though they do reverence Jesus as God's Son and Messiah, do not give Him the same kind of worship as they give to God the Father.
