Christadelphians hold that Jesus Christ is the literal son of God, the Father, and that Jesus was an actual human (and needed to be so in order to save humans from their sins). The "holy spirit" terminology in the Bible is explained as referring to God's power, or God's character/mind (depending on the context).
Jehovah's Witnesses teach that God the Father, Jehovah, is the only true God. They consider Jesus to be the "only begotten Son", God's only direct creation, and the very first creation by God. They give "obeisance" (homage, as to a king) to Christ, pray through him as God's only high priest, consider Jesus Christ to be Mediator and Messiah, but they believe that only the Father is without beginning, and that the Father is greater than the Son; only Jehovah therefore is worthy of highest worship. They believe that the Son had a beginning, and was brought forth at a certain point, as "the firstborn of all creation" and "the only-begotten". They identify Jesus as the Archangel Michael, mentioned in the Bible at Jude 9. They believe he left heaven to become Jesus Christ on earth, and that after his ascension to heaven he resumed his pre-human identity. This belief is partly based upon 1 Thessalonians 4:16, in which "the voice of the resurrected Lord Jesus Christ is described as being that of an archangel". They also cite passages from the books of Daniel and Revelation in which Jesus and Michael take similar action and exercise similar authority, concluding these scriptures indicate them to be the same person. They do not believe that the Holy Spirit is a person, but consider it to be God's divine active force.
