In their statement on the Church of Nigeria website, seven dissenting primates mention that "they represent more than 30 million Angicans." I note that the conservatives like to mention numbers, except when it's not convenient.
It would not have done to mention that they represent a minority of Anglicans (30 million out of 77 million) or that they are 7 out of 38 provinces. No, they wanted to make their numbers look as impressive as possible.
Well, speaking of numbers, what about ECUSA? When the church's democratic process works, they don't like it. But those votes are numbers. A majority of Episcopalians have indicated their preferences for women's ministry, the welcome place of gays & lesbians, the 1979 prayer book, and so on. But these votes (numbers!) are often dismissed for one reason or another. (Jan Nunley notes some "fun with numbers" on her blog.)
So here are a couple of numbers questions, so-called Global South primates: if it's about bigger-is-better, then why don't you join with Rome? If it's about numerical growth, why don't you become Mormons or Muslims?
No, you know that it's not really about numbers. So why mention them?
