Actually there are only 900 million Catholics<quoted text>
Believing and Putting into practice are two different things.
Whilst there are 2.5 Billion Catholic Christians in the world today, there is "Not a Single Country in the world" which is run according to Catholic beliefs!!
So there is not a Single Catholic Nation in the whole world.
And the same applies to Islamic Nation too. There are many Muslim countries in the world, but not a single Islamic country.
And there is a struggle in Muslim countries to become Islamic, whilst the Christians are "content" to live as they are and there is no move to turn their countries into Catholic country.
Therefore these 2.5 Billion Roman catholics in reality mean nothing!!
and there is one country run 100% along catholic beliefs, its call the Vatican City.
Get you facts right stupid.
