> Fundamentalists and evangelicals sometimes refer to themselves as literalists or biblical literalists. Sociologists also use the term in reference to conservative Christian beliefs which include not just literalism but also biblical inerrancy

> Islamic fundamentalists are of the view that Muslim-majority countries should return to the fundamentals of an Islamic state that truly shows the essence of the system of Islam, in terms of its socio-politico-economic system. Islamic fundamentalists favor “a literal and originalist interpretation” of the primary sources of Islam (the Quran, Hadith, and Sunnah),seek to eliminate (what they perceive to be) “corrupting” non-Islamic influences from every part of their lives

And so on !

Integrism is an antiquated form of Catholic chauvinism, an echo of Constantine. I’ve never seen fundamentalism applied to Catholicism.

Pope Francis did it : "there’s a traditionalism that is a rigid fundamentalism; this is not good. Fidelity on the other hand implies growth. In transmitting the deposit of faith from one epoch to another, tradition grows and consolidates itself with the passing of time, as St Vincent of Lérins said […] 'The dogma of the Christian religion too must follow these laws. It progresses, consolidates itself with the years, developing itself with time, deepening itself with age’.”

Some scholars describe certain Catholics as fundamentalists. Such Catholics believe in a literal interpretation of doctrines and Vatican declarations, particularly those which are pronounced by the Pope, and they also believe that individuals who do not agree with the magisterium are condemned by God. This is considered a pejorative designation. The Society of St. Pius X, a product of Marcel Lefebvre, is cited as a stronghold of Catholic fundamentalism.
