Answer:
Today, the motto is controversial. One side argues that a "separation of church and state" is needed, advocating the removal of the motto from all public use, including coins and paper notes. It is argued that religious freedom includes the right to believe in the non-existence of a God and that the use of this motto infringes upon the rights of non-theists. It is argued that any involvement of God by the government is unconstitutional. Others also claim that this motto was only adopted to oppose the Soviet Union, where atheism was prevalent, but this argument slips in the notoriety of the phrase from the times of the American patriarchs. Another side of the argument argues that the separation of church and state means that Congress can not impose a religion of the state on the population, and that this separation of church and state is a legislative invention unintentionally by the founders of the country. They argue that religious language is used in the documents that founded the United States, such as the Declaration of Independence, although opponents claim that the statement is only a historic, unofficial document of the US government. The motto, however, represents part of the American culture, being traditionally associated to the country, although it deposed its religious character. In addition, some believe that Christian religiosity was one of the fundamental elements for the creation of the American State. But there are also those who consider the opposite.
According to the Supreme Court, the phrase does not violate the provisions of the First Amendment, since it only refers to a God as a superior being, without subscribing to any form of religion or organized belief.
