Catholic priest Humberto Alvarez sprays holy water from a water gun to bless a crucifix during mass at the Ojo de Agua church in Saltillo, in the northern state of Coahuila February 17, 2013. Alvarez wears robes with cartoon characters and uses a water gun to bless the congregation when conducting children's mass, but slips back into his regular robes when officiating mass for adult believers.
