Abortion is, as we all know, one of the most painful and controversial spiritual issues of our day. The Goddess religion has no hard-and-fast ruling on when a clump of fetal cells becomes a being. In fact I was taught that the moment varies greatly with individual pregnancies. Some women have a sense of new life even before conception. Others may not feel that the fetus in their womb has taken on a soul until the time of quickening. This is one of the mysteries. Is is in our encounter with the mysteries of birth and death, growth and suffering, pleasure and sorrow, that we meet the Goddess. So to take away our right to have that encounter, to face that often painful and difficult choice, is to deny a woman's deepest spiritual self. For that reason, Pagans on the whole are strongly in favor of choice - although, of course (as with everything), individuals will differ widely in their opinions.
