significance, the position of the Catholic Church continues to affect the behavior of significant community and quasi-public institutions. Although they may be supported in large part by tax monies, Catholic hospitals and the equally extensive Catholic social services network are bound, by the very nature of their affiliation, to refuse to provide services deemed ''illicit" or even to refer their quasi-public clients to other facilities, assuming that they are available elsewhere in the community. Finally, although it is probably true that most Americans do not view abortion "as a method of family planning" in the sense that they would make a deliberate decision to use it as such, it is also clear that neither in science, in practice, nor in law is there a "bright line" to be drawn or a "wall of separation" to be erected in "matters so fundamentally affecting a person as the decision whether to bear or beget a child," in the words of the U.S. Supreme Court.
