SJ's post sums up what I have gathered about modern Christianity's approach to the whole deal. I have also read this elsewhere. I never say 'the Bible' doesn't support women enjoying their bodies and processes, I say 'Christianity' as a tradition, as an institution.
And, honestly, Dustmite...nothing I would honestly call pain in my birth! I know women who enjoyed their births more than I enjoyed my DS's...so there :P
Also, I just can't abide by the thought of birth being relegated to a hardship - it just doesn't align with my experience and those of people I know!
