You don’t worship the serpent.. no one prays to the serpent or cherubims.. Mary is worshipped.. she has special days- maybe even special Mariology classes... Mary if I am not mistaken is sinless in RCC. The coronation in Revelation is about Israel unless Mary is queen of Israel (maybe because we know she is called the queen of heaven).. only Enoch and Elijah that I remember are up in heaven without dying. The bible doesn’t discuss her death not because she didn’t die but because she isn’t important to our salvation. Certainly a miracle like Enoch or Elijah would have been recorded. The bible teaches us Jesus and the Holy Spirit make mediation and intercession for us. Thats 2/3 of the Trinity mediating to the Father for us.. That is in the bible.. Not making it up.. Why go to those nonomnicient dead people when you have Christ and the Holy Spirit living in you to mediate?
