There seem to be a confusingly large number of Christian churches (Catholic, Lutheran, baptists, evangelicals, Presbyterians). Could someone point me to a good overview that lists the mainstream ones, shows the main doctrinal differences, and also how they map between different countries. For example the German "Evangelische Kirche" seems quite different from the what in the US is called "evangelical".
