Isn't the idea that the savior of mankind had to come from the conception of a child in the absence of sexual intercourse with a man - insulting to our gender?
Immaculate Conception: for Jesus to be a
deity (God manifest in a human body), Catholic dogmatics had to get around the problem of
original sin, something all of us are born with, according to Catholic teaching. The appropriate authorities resolved the problem by making Mary sinless from conception (ie. she wasn't born under the shadow of original sin), and the Holy Spirit obviously doesn't suffer from that defect.
Virgin Birth: for Jesus to be the
Son of God (God manifest in a human body), he had to have God (through the Holy Spirit) as his 'biological' father, not any human male. The problem isn't sexual intercourse; it is of parentage.
