Although one might be tempted to think of mathematics as a wholly secular discipline, historically that's far from accurate.  

Today we have two different but essentially related perspectives on spirituality and math.  Pictured above:  math majors and professors from Asbury College.  On the "First Friday" of every month, they get together in thematically related costumes and jewelry, such as in the Star Wars pic above.  One math student explains her devotion as follows:

“I lot of people think I’m crazy for it,” said Kelly Christensen, a junior mathematics major from Canfield, Ohio. “They say, ‘Do you really enjoy pain?’ It is hard, but we like to think of math as the language of God. Mathematics can be seen throughout creation.”

Of course, some people extend the creation metaphor to the fullest.  Sharon Robbert, a professor of mathematics at Trinity Christian College, has placed on the web an array of math-related meditations.  Under such categories as "multivariable calculus" and "discrete structures" you can find such devotionals as "Secant Lines and Sanctification" and "God's Zero Tolerance for Error."
