The Church is a moral authority. As such, it can teach people that homosexuality makes Jesus unhappy, that taking BC pills really ticks off the Holy Spirit, than both of these make God really, really angry.
But there is no reason that the Church has that can justify it getting a special dispensation to deny its workers birth control pills if they desire them. There will be no pleasing the Catholic bishops. The Church hierarchy refused for four centuries to admit it was wrong to chastise Galileo for claiming that the Sun did not revolve around the Earth, because to its logic, Man had to be at the absolute center of Creation. The Church insisted on this for centuries after it was conclusively PROVEN to be false. They apologized for Galileo and abolished the Holy Office (i.e. the Inquisition) during my lifetime. There is no arguing with the stubborn idiocy of the Roman Catholic Church. The Church is, quite simply, an ass.
