Contradiction with Matthew 4:10
Revelation 5:12 speaks of worship directed towards the Lamb, while Matthew 4:10 emphasizes worship should be towards God alone, thereby raising questions on the scope of worship.
Matthew 4:10: Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.
Contradiction with Isaiah 42:8
Isaiah states that God does not give His glory to another, yet Revelation 5:12 attributes all power, wealth, wisdom, strength, honor, glory, and blessing to the Lamb, which suggests sharing God's glory.
Isaiah 42:8: I [am] the LORD: that [is] my name: and my glory will I not give to another, neither my praise to graven images.
Contradiction with John 5:23
John emphasizes honoring the Son just as the Father, but Revelation 5:12's focus on the Lamb alone for worship might be seen as elevating the Lamb's status in a way that appears separate from this co-honor.
John 5:23: That all [men] should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him.
Contradiction with Exodus 20:3
Exodus highlights having no other gods and directs focus solely on God, while in Revelation 5:12, the Lamb is given praise and worship, raising questions about exclusivity.
Exodus 20:3: Thou shalt have no other gods before me.
