Christian Aid in Japan To "Believers" Only???

While reading this, I was struck by the term "believers." It could of course, be a simple mistake of grammar that made this entreaty look exclusive, but I think not. Not the way to  get converts, guys!

CHARLOTTESVILLE, Va., March 18, 2011 /Christian Newswire/ -- The Christian Aid relief coordinator for Japan is calling Americans to pray and collect aid in Sunday services for the Fukusima families who lost loved ones in last week's killer quake.

Christian Aid Mission is sending the aid to Japanese believers working among residents evacuated from the nuclear reactor town on the northeastern coast of Japan. Fukusima is located just below the epicenter of the quake near Sendai.
