There is complete religious freedom within the country and, by law, the government may not collect statistics on religious affiliation. However, Catholic priests, Protestant pastors, and Jewish rabbis are paid by the state. The country is historically Roman Catholic and it is estimated that over 90% of the population are nominally members of this church. The largest Protestant denominations are Lutheran and Calvinist. About 6,000 people are Muslim, about 1,500 are Greek Orthodox, and about 1,000 are Jewish. There are also small communities of the Baha'is, Mormons, Jehovah's Witnesses and Members of the Universal Church. It is believed that the number of atheists is small, but growing.
