But it is not given to religions to endure forever.

They necessarily undergo transformation with the intellectual development of man.

How many countries are there professing the same religion now that they did at the birth of Christ?
It is estimated that the entire population of Europe is about three hundred and one million.

Of these, one hundred and eighty-five million are Roman Catholics, thirty-three million are Greek Catholics.

Of Protestants there are seventy-one million, separated into many sects.
