Hello kiltmaker,
Doing a quick search on abortion and sacrament led me to some excerpts from The Sacrament of Abortion by Ginette Paris:
"Artemis had a reputation for liking bloody sacrifices, including human ones ... a practice that has given paganism such a bad name.... The story of Artemis claiming Iphigena as a sacrifice can be told and understood in more than one way ... in one, Iphigenia is a victim, offered in sacrifice on the altar of Artemis; in the other Iphigenia becomes a heroine, and sacrifice takes on a different meaning. Since abortion is a kind of sacrifice, I believe an exploration of this myth may open up fresh avenues of thought." (p. 34)"Our culture needs new rituals as well as laws to restore abortion to its sacred dimension, which is both terrible and necessary." (p. 92)
"Abortion is a sacrifice to Artemis. Abortion as a sacrament for the gift of life to remain pure." (p. 107)

Its a mistake to make general statements about anyones beliefs so, would it be fairer to state that some, if not most Wiccans believe that abortion is a sacrament you are, as a pro-life pagan, obviously an exception to this statement.
