“The Catholics say that Jesus was conceived immaculately, not Mary. Maybe you are trying to say that Jesus was conceived in the womb of Mary in an immaculate manner.”
You are absolutely wrong about that. The Immaculate Conception refers to the conception of Mary, NOT Jesus. Look it up.
That’s why Rush’s use of it sounds so ignorant.
For some reason I thought Jesus was conceived into a human being, not Mary, but I guess I have it wrong.
