Sorry, I missed that. You still seem unable to grasp that Catholics do not believe Mary had other children and that scripture backs it up. As far as the pain of childbirth, the Immaculate Conception might preclude this.
In the very same passage of Genesis, "emnity" is places between "the woman and her seed" and satan and "his seed" -- this is ONE EMNITY, not two, and if the emnity between Christ and satan is absolute and eternal, then His mother enjoys the same.
