son didn't I tell you to stay away from those creepy old guys?? 
Okay, now it's getting a little creepy.
Creepiness knows no bounds.....
So.....howz about them Ecumenical Councils, anyway?
All 9 1/2 Ecumenical Councils are doing quite well 
For the RC's or for the Orthodox? 1/3 of the council of Basle is ok with the RCC, and 1/4 of Constance, and then of course Florence trumps the others on papal supremacy. Even Vatican I is in fractions as the official name of the RCC there is indeed "Roman" whereas this was nullified by Vatican II which reduced it to "Catholic." We may have less whole numbers but also have less fractions. 
Well, I can google for the dates and details, but off the top of my head...
Nicea = 1
Constantinople = 1 (even though the actual council broke up, and was reconvened later, I'll still count this as one)
Ephesus = 1
Chalcedon = 1 (leaving aside that a large chunk of the Church rejected it, which I guess is true to a lesser extent for Ephesus)
Justinian's Thing = 1
That one in 680 = 1
Trullo = 1/2 (it met like 10 years after #6, so ain't no way I'm counting it as the same)
The 787 Icon council
Photian Council (the Orthodox one that sort of settled things down, not the Catholic one)
Palamite Councils (multiple councils, at least three, and maybe as high as six, but I'm fine with them be grouped together).
= 9 1/2
(yes, I'm only being 1/4 serious

)
