unbeliever.

The Archbishop of Tyre was the first to whom he confided his
doubts, knowing his interest with his master, Richard, who both
loved and honoured that sagacious prelate. The bishop heard the
doubts which De Vaux stated, with that acuteness of intelligence
which distinguishes the Roman Catholic clergy. The religious
scruples of De Vaux he treated with as much lightness as
propriety permitted him to exhibit on such a subject to a layman.

"Mediciners," he said, "like the medicines which they employed,
were often useful, though the one were by birth or manners the
vilest of humanity, as the others are, in many cases, extracted
from the basest materials. Men may use the assistance of pagans
and infidels," he continued, "in their need, and there is reason
to think that one cause of their being permitted to remain on
earth is that they might minister to the convenience of true
Christians. Thus we lawfully make slaves of heathen captives.
Again," proceeded the prelate, "there is no doubt that the
primitive Christians used the services of the unconverted
heathen. Thus in the ship of Alexandria, in which the blessed
Apostle Paul sailed to Italy, the sailors were doubtless pagans;
yet what said the holy saint when their ministry was needful?
--'NISI HI IN NAVI MANSERINT, VOS SALVI FIERI NON POTESTIS'--
Unless these men abide in the ship, ye cannot be saved. Again,
Jews are infidels to Christianity, as well as Mohammedans. But
there are few physicians in the camp excepting Jews, and such are
employed without scandal or scruple. Therefore, Mohammedans may
be used for their service in that capacity--QUOD ERAT
DEMONSTRANDUM."
