 At the time of Breyer 's appointment in 1994 , there were two Roman Catholic justices , Antonin Scalia and Anthony Kennedy , and two Jewish justices , Stephen Breyer and Ruth Bader Ginsburg . Clarence Thomas , who had been raised as a Roman Catholic but had attended an Episcopal church after his marriage , returned to Catholicism later in the 1990s . At this point , the four remaining Protestant justices — Rehnquist , Stevens , O 'Connor , and Souter — remained a plurality on the Court , but for the first time in the history of the Court , Protestants were no longer an absolute majority .
