To ascend for Mary is to do what Christ did: go to heaven under her own power. Mary, we teach, was assumed: taken up by God. That is consistent with her being given wings and going where the river of vomit does not reach her. Heaven, indeed, is merely inferred from that chapter, and were we to take it literally we would say that she was flown to some remote desert and not assumed to heaven.
Any inferring in scripture is first toward those passages that are similar to this one. They are in Daniel, Genesis, and earlier in this Revelation. The woman herself is best seen in the light of the OT prophets’ references to the woman (people of God) God desired to have for Himself. Unfortunately, she always adulterated herself and was rejected. This one, however, is faithful.
She is driven into the wilderness. She gave birth to our Lord. Mary was representative of her. The faithful who say “yes” to God.
There is definitely no assumption of Mary in this passage. In fact, too much makes it impossible to be Mary.
