Hieromonk Seraphim of Platina 1934-1982
One big mistake we can make about our Orthodoxy is being too loose, too “liberal” about it. This comes from ignorance. Some Orthodox people think that the Orthodox Church is nothing more than the Russian or Greek equivalent of the Episcopalian Church; with such an idea of course, one is not going to try very hard to bring anyone to the Orthodox Faith. This is the error of the ecumenical movement, which arranges meetings and conferences with non-Orthodox Churches, not with the aim of bringing them to the true Faith of Orthodoxy, but on a basis of worldly friendship, in order to speak of the secondary things which we have common with them, and to gloss over the differences which separate us and an awareness of which make them eager to accept the Orthodox Faith. This is not to say that all meetings between Orthodox and non-Orthodox Christians, even on an official level, are wrong — but only that as ordinarily practiced these meetings are not an Orthodox witness to the non-Orthodox, as they should be.
With all respect to the views of the non-Orthodox, we are not living our Orthodox Faith rightly if we do not make others somehow aware of of the differentness of Orthodoxy. This does not need to mean arguments and polemics about aspects of the Faith, although these might arise after others have become interested in Orthodoxy. The very way one leads one’s Orthodox life, if one is serious about fulfilling the commitment of being an Orthodox Christian, is already a witness to others…
Yet another mistake made by contemporary Orthodox is what one might call the “fortress mentality”: we have the truth of Orthodoxy, and the times are so bad that our chief activity now is to defend it against the enemies on every side. Often this mentality goes overboard in finding “betrayers” and “heretics” in the midst of Orthodox Christians themselves, and very often it is so concerned with its own “correctness” and the “incorrectness” of others that is has very little strength left to preach the Gospel of salvation even to the Orthodox, let alone to those outside the Church.
Now, Orthodoxy is indeed the correct teaching and the correct worship of God, and this is why this temptation is so easy to fall into. But we must remember that Christ Himself was constantly accused of being “incorrect” by the chief priests and pharisees of His time, and we have to remember that correctness in itself is nothing, and can even cause us to lose our soul, if we do not have first of all something much more fundamental and deep — the “one thing needful” for or salvation. This “one thing” might be called “living faith,” and it is inseparable from something which is all too lacking in the Church today — evangelical fervor. If we have found the true Faith after our own often arduous search, we cannot help but want others to share it. (The Orthodox Word 2002 no. 226 p. 247-248, 250-251)
