In ch. 1 I have made the corrections.
About ch. 2:
In 2.1, talk about the historical role of Greek Orthodoxy in shaping international relations, that is, about the Patriarchate of Constantinople before the autocephaly of the Greek Church, as you started with the introduction. I would put the second paragraph with Syria in 2.3, as I have corrected it, and the last one that the professor says should go further down, maybe in 3.3.
In 2.2 he wants you to argue that the main concern of the Orthodox Church of Greece was the geographical territory and national identity, and to connect this with the main issue, that is, that there were no international relations beyond what concerned the national interest and the national identity before Christodoulos, apart from few exceptions.
In 2.3 you will join the section that refers to the changed international relations with the new era brought by Christodoulos.
In 2.4 in the conclusions you write that it is obvious that the activities of Orth. Church in Greece increased, although he himself was not particularly progressive, but you have not talked about this in the previous sections. Justify it in 2.3. I deleted the last two paragraphs, so you may need to add a couple more words so it doesn’t seem redundant.
About ch. 3:
3.3 is too small. He wants you to develop who were the theological circles that supported the secession from the patriarchate of Constantinople for its pro-Western stance, that is, to analyze what exactly happened. Do you mean the meeting of Athenagoras with the pope in the 1800s or some other incident with Bartholomew or the general climate? Also, to analyze why there was instability in the distribution of power between the churches and the patriarchates.
In 3.4 the professor tells you that it is not true that Athens and Thessaloniki had two different versions of orthodoxy, because their original differences were eliminated. You should instead focus on the fact that they were competing to represent Greece, as well as on issues of national identity
