That is interesting...even your scholars talk about the importance of textual criticism, and their approach to it. Here is just one link to a recording on Ancient Faith Radio you might like to listen to: http://www.ancientfa...ch_to_the_bible
Actually, Andres, textual criticism is a tremendously Orthodox thing to do. In fact, it is an essentially Orthodox practice. Again, I would encourage you to study the term. It is apparent you do not know what we are talking about.
I'll give you a short cheat sheet: Textual Criticism is the practice of evaluating various manuscript traditions of a text (be it Scripture, the Fathers, or Dr. Seuss), in order to discern the original wording of the text. Any Bible you have in your home...albeit Greek, English, Spanish, or any other is the certain work of the process of textual criticism.
You have no commentary that tells you whether the Alexandrian, Caesarian, Byzantine, or Western textual traditions are the correct rendering. Textual Criticism is the study of these things, in order to give you every single Bible you have ever read (especially your Greek one).
Forgive my butting into this debate, but on this one point I feel I must contribute something.
The categorizing of texts into text-types such Alexandrian, Byzantine, Caesarian, and Western (the latter two being debatable) is essentially not the way the Church looks at the scriptures, that is not to say such is wrong especially when looked at as a loser tradition rather than a set text-type but it is a western scholarly way of looking at the Scriptures as a text not the Church's way of reading the Scriptures. Remember the Church pretty much uses the "Byzantine text type" exclusively, we do not look to textual criticism for the "correct" readings. Secondly the Church understands the Scriptures as being part of the wider Holy Tradition not as being alone, and therefore interprets them within that Tradition with the Mind of the Church, hence the need for an exact text is not as great as for Protestants who have to interpret the Scriptures using their own surmisings.
Also it is incorrect to say Textual Criticism gives us every bible we ever read, Orthodox Greek bibles are not products of Textual Criticism nor are those in Slavonic, Georgian, Syrian, ect... The only exception which could be made is the Patriarchal text but I highly doubt it can in reality be said to be the product of Textual Criticism at least by western academic standards.
