It is obvious to me that the bible teaches that mankind is in a fallen state - and this has been the case from the very first humans and will be the case til the very last human. I don't think we need a literal Genesis to conclude that. This is a universal condition and I've fallen just like "Adam".
		
		
	 
Sure, mankind is in a fallen state, but it is in this state because "through 
one man sin entered into the world, and death through sin, and so death spread to all men..." (Romans 5:12), for "by the transgression of the 
one the 
many died..." (Romans 5:15), and "For as through the 
one mans disobedience the 
many were made sinners..." (Romans 5:19) just as the apostle Paul explains in scripture. 
The apostle Paul goes on to explain that: "So also it is written, The first man, 
Adam, became a living soul. Not only does sin and death originated with ONE, real, man but Paul recognizes his as the first man, not as mankind in general. Paul goes on in 1 Timothy 2: "For it was 
Adam who was first created, 
and then Eve." Paul believes that BOTH Adam and Eve are real, not just representatives of humanity. 
Luke gives us a genealogy of Jesus in Luke 3. Verse 38, "the son of Enosh, the son of Seth, the son of Adam, the son of God." Luke also believes that Adam is a real person. Jude also believes that Adam is a real person: "
in the seventh 
generation from 
Adam..." 
The words of the writers of the NT support a real Adam and a real Eve and support a literal Genesis. 
	
	
		
		
			As for mariology - I do not worship Mary, I think worship is for God alone. There are some strong types in the bible concerning Mary - as a second Eve, as a type of the ark of the covenant, as the davidic mother. None of these things deify her. I look at her the same way I look at Paul, but a little stronger. She had amazing faith - and is someone for whom I can look up to and use as a wonderful role model. Paul said "imitate me as I imitate Christ". I think a similar attitude is warranted about Mary.
		
		
	 
I did not suggest that you, or the adherents of the Catholic church in general, worship Mary. But your church makes specific claims about Mary that are based on Mary being a type of Eve, the new Eve. I posted some of the verses from the Catholic church catechism supporting this view in a previous post. If Mary is not a type of a real, living Eve then many of your church's Mariology can not be posited.

Unfortunately no. They create more questions.
