What are the 10 most important events in Church history?

What made this difficult (aside from my general ignorance) is how to deal with historical events that profoundly shaped Church history, but aren't distinctly Christian (Gutenberg's printing press, destruction of the Spanish Armada, invention of Twitter...). Another question is how to deal with major events that fall within the scope of the "Church," but had relatively little impact on the trajectory of the gospel. The Great Schism strikes me as the prime example.

I decided to narrow my list to explicitly Church-related events that affected the trajectory of the evangelical faith. And I'm not cheating off someone else's list (except for Wiki's help on dates), so I probably brain cramped and left out something big. Oh, and I'm starting with the close of the canon. Here goes...

1. Constantine's Edict of Milan legalizes Christianity (313)
2. Council of Nicea articulates biblical Christology (325)
3. Conversion of Augustine (387)
4. Publication of Luther's "95 Theses" (1517)
5. Conrad Grebel ("re-")baptizes George Blaurock in Zwingli's Zürich (1525)
6. Publication of Luther's German translation of the Bible (1534)
7. Council of Trent formalizes the RCC's rejection of the Reformation doctrine of justification (1547)
8. Publication of Calvin's Institutes (definitive Latin edition, 1559)
9. Separation of church/state and freedom of religion in Rhode Island (1637)
10. William Carey initiates the modern missions movement (1792)

Obviously, there's a big gap in the middle, and nothing from the past two+ centuries, though the next five that I left out would shift that a bit. It's probably difficult at this point to evaluate any event from the 20th century objectively, but which do you think is most likely to be included by a 23rd century evangelical historian?
