Abortion is not defined as anything other than the removal of an implanted embryo, blastocyst or fetus.  There is no such thing as an abortion prior to implant and in fact most zygotes never implant in a woman taking no hormones or using any BC.  When an embryo does not implant that is not a death of a person or a person with a soul.  It certainly is not murder or Mother Nature would be guilty of mass murder every day.  An Embryo is a structure created by the unification of sperm and egg or the insertion of a skin, or other cell, into an evacuated ovum and then stimulated to divide.  So each and every cell in the human body has a potential to become a pluripotent embryo.  When does this structure become a person or have a soul?  No church has been able to adequately define that.  There are some scientifically uniformed bishops who believe human personhood begins with the unification of human sperm and egg.  That is ridiculous as Mother Nature (God) does not murder....
