How do you think that follows? If Jesus Christ is the living descendant of Adam, He's a descendant whether Mary was a sinner or not.

If Jesus the Second Adam is sinless,then He is the same as the First Adam was, in those blissful days in Eden before sin. In other words He has the same HumanNature 1.0 that First Adam had, before the Apple Incident.

How could he be a descendant of Adam if his mother lacked Adam’s sin nature?

Mary would have had to have been removed from Adam’s lineage somehow.

Fortunately, Mary was quite the sinner, as can be ascertained from each and every mention of her after his birth.
