I really wish you would consider thinking a little more before you post something like that.
First of all, the Church back then didn't have modern science to help articulate a more complete understanding.  Consider that heliocentricity wasn't considered a fact until Newton's laws became widely known.  The Christian Churches, including the Catholic Church, didn't accept heliocentricity until 1758.
Baptism is not performed on the dead; thus, no Christian burial.  If an unborn is aborted, then he or she is already dead.
"Thou Shalt not Kill" certainly covers abortion.
But I'm not making a religious case against abortion.  Michael started obfuscating by going down that line of thought.
Human life begins at Conception.  That is a verifiable, scientific fact as any embryology text book will prove by providing all the scientific details about human procreation.
