For People Who Think There Was No Historical Jesus

[Confused Ape]

Minor nitpick, we don't all call them -all- christians today because people are inclined not to give a shit, we used to cal them by their denominational names......it was a concerted political and social effort of the past 50 years or so that left us with the idea that there where christians in the world - as opposed to catholics and protestants, for example.

I suppose it depends on how one defines denominations. These days the general view is that Christianity is split into branches and the Protestant branch has different denominations within it.

Christian Denominations by number of members

This is a list of Christian denominations by number of members. It is inevitably partial and generally based on claims by the denominations themselves. The numbers should therefore be considered approximate. The list includes all the Eastern Catholic Churches affiliated to the Catholic Church, all the Eastern Orthodox and Oriental Orthodox churches with some recognition, relevant breakaway churches of the Catholic Church, the Protestant denominations and the Anglican churches with at least 0.2 million members, and all the other Christian branches with a distinct theological tradition.

Not all Christians regard every denomination as Christian, though. There are articles on the internet saying that Roman Catholics, Mormons and Jehovah's Witness aren't Christians, for example.
