Both of these religions are joined by graven images and thus idolatry.
Isa 44:9 They that make a graven image are all of them vanity; and their delectable things shall not profit; and they are their own witnesses; they see not, nor know; that they may be ashamed. 10 Who hath formed a god, or molten a graven image that is profitable for nothing? 11 Behold, all his fellows shall be ashamed: and the workmen, they are of men: let them all be gathered together, let them stand up; yet they shall fear, and they shall be ashamed together.
17 And the residue thereof he maketh a god, even his graven image: he falleth down unto it, and worshippeth it, and prayeth unto it, and saith, Deliver me; for thou art my god. 18 They have not known nor understood: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand."
