We may distinguish between three types of heretical ideas. The first is heresy in the classical sense, an attack on a specific teaching of the faith, such as the Divinity of Christ, the Procession of the Holy Spirit, the uncreatedness of Grace, or the Unity of the Church. A second type is constituted by the modern heresy of ecumenism, which does not so much attack any specific teaching of the faith, but rather adopts a new attitude to heresy in general, arguing that there is no such thing as One True Faith preserved by the One True Church, that the difference between truth and heresy is unimportant or even non-existent, that all denominations or religions are equally true (or untrue), or that, as one reviewer put it, “the greatest heresy is to believe that there is such a thing as heresy”. A third type consists in taking a true formula, declaring it to be the central truth of the faith, and then “restructuring” all the other dogmas around it – without specifically denying them, but nevertheless distorting them through the creation of this new dogmatic centre of gravity. This is the path adopted by the most influential thinker in modern Greek Orthodoxy, Fr. John Romanidis, and the large number of his disciples, including Metropolitan Hierotheos (Vlachos), Protopresbyter George Metallinos, Christos Yannaras and others.
There are links between these different types of heresy. Thus it is likely that the Protestant loss of faith in the dogma of the Church led to the disintegration of the Western Christian world, which in turn led to the need to “recreate” the Church in the form of a kind of coalition of denominations, which in turn led to the need to create a kind of doctrinal “lowest common denominator”, which in turn led to the despising of the concept of the One Faith that is characteristic of the heresy of ecumenism. And then there are links between ecumenism and “Romanideanism”…
Fr. John Romanides (1927-2001) was a member of the new calendarist State Church of Greece, an admirer of the Ecumenical Patriarch Athenagoras, a member of the Central Committee of the World Council of Churches, a participant in many ecumenical conferences and a key supporter of the Chambésy union between the Ecumenical (World) Orthodox and the Monophysite heretics. However, while being actively engaged in the ecumenical movement in this way, and subordinate to hierarchs who prayed with and recognized both the eastern and the western heretics, Romanides constructed a theological system that virulently rejected not only Catholicism and Protestantism, but also certain traditional Orthodox teachings on the grounds that they were “Augustinian” and “scholastic” – that is, heretical. Romanides taught that the theology that was taught in Greece in his day “is of western and Russian origin. No relationship with Byzantium.” And so he saw his own work as a revolutionary return to the true Orthodox teaching from the heresy of contemporary Greek and Russian theology.
