The watchtower claims that Jesus Christ is no longer a man, but is instead an angel. However the Bible says that the mediator is . . . . "the man" Christ Jesus.
"For there is one God, and one mediator between God and men, the man Christ Jesus; Who gave himself a ransom for all, to be testified in due time." 1 Timothy 2:5-6
Do you have the man Christ Jesus as your mediator ?, or do you reject the man Christ Jesus as your mediator, and instead have a Jesus (who is an "angel") for a mediator?
"But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. For if he that cometh preacheth another Jesus, whom we have not preached, . . . " 2 Corinthians 11:3-4
