This is true, and in addition, Christian monastic life has always been seen as a contribution of these people to society (through their prayers, etc.), even when the monks in question were hermits.
However, I think Jews also believe this. The people who devote themselves to the study of the Scripture/Talmud are performing a service to the rest of the community.
However, in neither case were Christian monks or Talmudic scholars urging homicide/suicide attacks on the surrounding society. Only Islamic "scholars" seem to do that.
Warning! This is a high-volume ping list.
