Jehovah's Witnesses do not teach that Jesus positively is Michael the archangel, but that from what the bible says of Michael it seems likely that this is so. In our encyclopedic "Insight Into the Scriptures" on page 393 we use terms such as "Scriptural evidence indicates," "This seems to imply," and "It is only logical, therefore," in discussing this subject.
We are not dogmatic about this idea as many on this sight seem to think. We believe the facts indicate we are right, but time will tell if we were right or not.
Either way, whether Jesus was named Michael previously or not, we know that he is the divine son of Almighty God Jehovah. There is none more powerful than he, none has more authority than he save his Father in heaven. (1 Corinthians 15:27)
When we pray we do as Jesus taught us to do. We pray to the Father in Heaven, Jehovah directly through Jesus. We know and teach that no one comes to the Father except through Jesus.(Matt 6:9)
I don't know why people slander us and say we teach the "doctrine of demons," since what we teach is from God's word directly.
I see complex language used here in one answer that we teach "a form of soul migration and angelic entity in-habitation." This sounds really terrible, doesn't it? But I think what it simply means is that angels can take the form of human bodies, and the bible is full of such instances. We also know that Jesus, after his death, appeared several times in human form and was visibly seen by many witnesses.
I also see a claim that "The bible teaches us that Jesus is our Kinsman Redeemer and that He placed His blood upon each of the four corners of the cross..." I would very much like to see any scripture that verifies this claim. Why don't slanderers back up their statements?
I also see the false notion that "Only God Himself could pay this price be our Savior and Repurchaser."
The bible does not say this at all. Rather, the bible says that to be our repurchaser required a perfect MAN to take the place of Adam, a perfect MAN that was lost to sin.
"For there is one God, and one mediator between God and men, a MAN, Christ Jesus, who gave himself a corresponding ransom for all..." (1 Tim. 2:5, 6) [caps mine]
God's perfect justice required "eye for eye, tooth for tooth" and "soul for soul." In the case of Adam who had been created perfect, it required a perfect man to ransom a perfect man. It is proof of God's love for us that he sent his only begotten son to fulfill this job for our salvation. Jesus became a perfect man and sacrificed his life for us; paid the ransom for us that Adam had lost. It required a Man to fulfill this ransom, not God himself.
