Religion

Even though it is a secular nation, Roman Catholicism, Judaism, Lutheranism, Islam, and others are acknowledged by the government as legally required religions. Since 1980, the government has outlawed the collection of data on the religious beliefs and practices of its citizens. However, 87% of the nation's population is believed to be Catholic Christians, according to a 2000 estimate by the CIA Factbook. From the city of Trier, Christianity spread to Luxembourg. First to be Christianized were the cities. Long after Christianity arrived in the nation, pagan practices continued to be practiced in rural and isolated locations. However, Christianity had a stronghold in the region by the Middle Ages. Luxembourg's Catholic Church has received funding from the government ever since 1801.

A sizeable portion of the population of the nation also practices Protestantism. In Luxembourg, there are several Protestant churches and denominations. Some of the biggest Protestant churches in the nation are the Church of England and the Protestant Church of Luxembourg. In Luxembourg, Protestantism is the largest minority religion. About 15,000 to 18,000 people in this area practice this faith. The percentage represents around 3.5% of the total population of the country.
