Lydia, though its is not specifically noted if mary had sinned or not Mary was human therefor she would fall under the "all" have sinned (Romans 3:23) and there is no record of mary ascending into haven and just because someone ascendes into heaven dosent mean that they never sinned Elijah ascended into heaven 2 kings 2:1 and again no mention of his not sinning and again if anyone has anyquestion pls feel free to contact me im on face book :D
