Religion
Almost half the people in the Netherlands don't subscribe to any religion. After this, the country is divided into believers of a number of religions, the largest of these being Catholicism, followed by Protestantism. There is also a decent sized Muslim minority as many of the Indonesian immigrants are Muslim.
Catholicism is a Christian religion that is one of the first Christian religions (founded after the death of Jesus in about 30-33 AD). Catholicism believes that there is a single God who created everything, a savior, the son of God, Jesus Christ who is the forgiver of sins, and there is the Holy Spirit, which makes up the last part of the Holy Trinity. Catholics follow the teachings of the Bible, consisting of the Old and New Testaments. Much of the faith is based on the life and teachings of Jesus, which is found in the gospels (in the New Testament).
Protestantism is a general term referring to nearly every Christian religion that is not Catholic or Orthodox. Like all Christian faiths, Protestants believe there is one God and that His son, Jesus is the savior and forgiver of sins. Protestants also believe that the Bible, which includes the Old and New Testaments, is the only true word of God. Due to this reliance on the Bible, nearly every protestant faith, and even individual, may interpret the Bible differently, which has led to a huge number of Protestant churches.
