Theology 101: At the very least, she would need a savior to cleanse her of original sin.
I thought the idea behind the Immaculate Conception was that Mary was exempt from original sin? So if the IC is true, why did she need a Savior considering that she never sinned? Did she lie?
She needed a savior to preserve her from original sin and provide sanctifying grace (cleanse is the wrong word to use).
