Buses, Bibles & Spanish lessons

Taking spanish lessons in Cordoba for 2 weeks. Took an overnight bus from Buenos Aires to Cordoba. It was my first overnight bus so I dont have anything to compare it to - but it seemed a bit odd that there were bibles on each seat wrapped up in the blanket & pillow they give to you...it got even odder when the bus hostess handed to everyone a comment sheet, a welcome note & a copy of some verses from Romans 2!
