Interesting. Was there a particular reason? I mean it doesn't seem that important who was ultimately most important. All three were probably huge in their own right. Good to know the history though.
St. Gregory the Theologian was the best, but the partisans for the other two saints couldn't be made to see reason, so being saintly and humble, St. Gregory allowed all three to be venerated together so as to maintain brotherly love and unity on earth. This story is not true, but it's how I think about it.
for another view.
Regarding the OP... since I last posted on this thread I have wondered what the negatives and positives of such a project would be. I am generally a fan of getting as much good/verified information to people as possible and then leaving it to them to do right by it. And there would obviously be advantages in learning about the faith, constructing/researching for sermons, etc. However, I do think there are also dangers in this kind of thing. A major worry is that such lists or resources can give people a sense of knowledge that is well beyond the means of what they actually have. They may not know the culture, context, language issues, and on and on, and all they can think is "Well I based my opinion on the Fathers, I read a bunch of them, so how can I get things wrong?" It is perhaps comparable to Protestants, who continually read and study the Bible, and think they are growing with each day to a better understanding. And maybe they are, I hope so anyway. However, this can also lead to a prideful sense of mastery of a topic or text or whatever that isn't actually there.
Anyway, thoughts on the pros and cons of such sites/resources?
