Writing for the Church of Greece|Greek Orthodox Archbishop of America|Archdiocese of America, Rev. Protopresbyter George C. Papademetriou has written a summary of classical Christian and Greek Orthodox Christian views on the subject of the salvation of non-Christians. In his paper ''An Orthodox Christian View of Non-Christian Religions'' writes:
:In our times. Professor John N. Karmiris, University of Athens, based on his studies of the Church Fathers, concludes that the salvation of non-Christians, non-Orthodox and heretics depends on the all-good, allwise and all-powerful God, who acts in the Church but also through other "ways." God's saving grace is also channelled outside the Church. It cannot be assumed that salvation is denied non-Christians living in true piety and according to [[natural law ]] by the God who "is love" (1 John 4:8), In his justice and mercy God will judge them worthy even though they are outside the true Church. This position is shared by many Orthodox who agree that God's salvation extends to all who live according to His "image" and "participate in the Logos." The Holy Spirit acted through the prophets of the Old Testament and in the nations. Salvation is also open outside the Church.
As is common in many other faiths, the question of salvation for those outside of Orthodox Christianity is understandably secondary to what the Church expects of its own adherents. As St. Theophan the Recluse put the matter: "You ask, will the heterodox be saved... Why do you worry about them? They have a Saviour Who desires the salvation of every human being. He will take care of them. You and I should not be burdened with such a concern. Study yourself and your own sins... I will tell you one thing, however: should you, being Orthodox and possessing the Truth in its fullness, betray Orthodoxy, and enter a different faith, you will lose your soul forever."
====Modern (post-Enlightenment era) Christian views====
Many 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 [http://sebomenoi.org/index.php/Petrine 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.
