Poor z, doesn't know.

Every other human conception results in the girl no longer being a virgin.
Not necessary anymore. Have you heard of artificial insemination? It is possible without artificial insemination for women to conceive without penetration (ie sex)

Mary remained a virgin but now pregnant with Christ.
What is more likely? Mary had sex with a bloke or with a (the) Spirit?

Mary then became the mother of Christ but beyond that continued to be a normal everyday person.
Fair enough. Some say the mother of God.

Vatican teaches that Mary (in her death) has other powers.
Being the mother of Christ, I guess, makes her special in the Vatican's and every Christian's eyes.
