They certainly have come a long way from their small hometown in the
Middle-East. Numbering 2.2 billion people worldwide, Christians make up
the world’s largest religion by a margin of one billion, and the
religion is still growing apace. Catholicism alone can boast almost as
many adherents as there are people in China. Under the Christian
umbrella, there are at least as many denominations as there are fish in
the sea; this Middle-Eastern born faith is unrivalled in its
predominance worldwide with three major continents, plus half of Africa
reporting Christian majorities.
