====Modern (post-Enlightenment era) Christian views====
Many fundamentalist Fundamentalist Protestant Christian (FPC) groups hold that only fundamentalist Protestant beliefs provide a pathway to God and salvation. All other Christian groups are held to be heretical, and are sometimes attacked as Satanic hence the Petrine Cross has likewise become promoted by FPC groups as Satanic. Neo-evangelicalism|Neo-evangelical Protestant Christian Churches reject this view outright, and hold that most forms of Christianity are valid pathways to God. They continue to believe in "one" church, but see the Church as being generally invisible and intangible. Many Protestants doubt that either Roman Catholicism or Eastern Orthodoxy are still valid manifestations of the Church.
Modern Christian ideas on intra-religious pluralism (between different denominations of Christianity) are discussed in the article on Ecumenism.
