Chiller channel unnamed show? Priest vs. demons?

I was watching this show on the Chiller channel and I have no
recollection of the title. It is about a priest who fights off demons
who possess certain people throughout the show. One person he helped
was a young priest from India who had leopardsy as a child. He
idolizes Mother Theresa (who cared for him when he was sick) and later
on he was miraculously healed. But he claims Mother Theresa's healing
touch didn't heal him but a demon did. The demon often gives the young
priest back his leopardsy on his hands or other parts of his body if
he continues to try to free his body from the demon or do things the
demon does not approve of.
Another scene I briefly remember from another episode was another
young man who has visions of Mary talking about the son of God or
something of that sort. This young man is Muslim and has a loving
mother. I remember the father dying in camp somewhere in the Middle
East or being shot. The mother tells her son "How can Jesus be the son
of God? He is a preacher!" And the priest comments, "The devil loves
it when Muslims and Christians argue with blood" ( Or down one another
throats but something of that nature.)
In the beginning episodes with the priest he has an African American
nun work as his secretary or his assistant. The demons against the
priest eventually goes after the people who he cares about and ends up
going after her. When the nun is naked and turns on her shower. These
beads which released poisonous gas substituted the water and she dies
tragically. A demon has possess another priest who put the gas beads
in the shower. ( This priest was born Jewish whose family has been
killed during World War II.) I remember him saying something like "The
Jewish God isn't so different from yours" Referring on how God abandon
his family during the Holocaust and abandons the priest war against
the demons.

I didn't get to finish the series and I hope my very poor descriptions
could be of any use.Each episode was around 1 hour long and I think it
was a special premiere or marathon for Chiller. Ever since I saw it I
can't stop thinking about it and have a great desire to finish the
series and find out the ending. Your help is greatly appreciated!
