you did not answer the question. Why did she need to be sinless? Couldn't God have created Jesus sinless, just as easily as he could have Mary?

Also, why would a woman who is sinless need a savior as she declares in Luke 1:47? What does she need saving from?

The second part is answered in the doctrine. She was, we maintain, sinless by the saving work of Christ. Her sinlessness is, inter alia an eschatological foretaste of what is promised to all the elect.

Again, not tyring to persuade, but rather to clarify.

[Campion]

Also, why would a woman who is sinless need a savior as she declares in Luke 1:47? What does she need saving from?

You have it backwards. Her savior is the one who made her sinless, and him making her that way is part and parcel of how she was saved.
