English is the most commonly taught second language and nearly the entire population is bilingual. Other languages are taught in Denmark, including German, French, and others, but to varying degrees. Copenhagen is also home to numerous immigrants who speak a huge number of languages natively, although most also learn Danish or English as a means to communicate.
Religion
Evangelical Lutheran is the country's official religion, although full religious freedoms exist in Denmark. Still much of the country is Lutheran, but the very small minorities that are not tend to adhere to other Christian religions, such as Catholicism.
Lutheranism is a protestant religion that was founded by and named after Martin Luther, who led the Protestant Reformation. Like all Christian and protestant faiths, Lutherans believe there is one God and that His son, Jesus is the savior and forgiver of sins. Lutherans also believe that the Bible, which includes the Old and New Testaments, is the only true word of God. It is generally in the interpretation of the Bible that protestant religions vary and this is true in the case of Lutheranism, which tends to interpret the Bible quite differently from Catholicism, which was the religion Lutheranism separated from.
