These are the reasons I hate the doctrines of JWs.
JWs refuse to accept Acts 4:12 that the only name given under heaven by which mankind must be saved refers to Jesus name alone. They insist its Jehovah plus Jesus.
JWs insist that Jehovah is the name of the father and refuse to accept that Jesus is the only name used in baptism Acts 2:38 by the apostles. Even as he commanded his disciples Matthew 28:19 baptize them in the name of the Father Son and Holy Spirit. Ergo, since Jehovah is not used by any of the apostles in baptism it is not the name of the Father.
JWs refuse to accept PHilippians 2:9 that Jesus is the name above all names, therefore Jehovah is an inferior name or below the name of Jesus.
