Churches based on Reformation ideas have multiplied into different forms, especially in historically Protestant countries. Even in much of Latin America, which is historically Catholic, Evangelical churches, which follow many of the Protestant ideas have greatly expanded. In the 20th century, some countries still had state churches, but also allowed full freedom of religion. In these countries, conflict between Protestant and Catholic Christians have become less important. They have to work together to confront a more secular society. In 2016 Pope Francis praised Luther in a prayer service commerating the 500th anniversary of the Refomatiom. In turn, some Protestant churches have embraced some Catholic worship traditions, and others have praised them for their stand on social issues.
