The anarchists are of Christian origin. Physical science is of
Christian origin. The attack on Christianity is of Christian origin.
There is one thing, and one thing only, in existence at the present
day which can in any sense accurately be said to be of pagan origin,
and that is Christianity.

The real difference between Paganism and Christianity is perfectly
summed up in the difference between the pagan, or natural, virtues,
and those three virtues of Christianity which the Church of Rome
calls virtues of grace. The pagan, or rational, virtues are such
things as justice and temperance, and Christianity has adopted them.
The three mystical virtues which Christianity has not adopted,
but invented, are faith, hope, and charity. Now much easy
and foolish Christian rhetoric could easily be poured out upon
those three words, but I desire to confine myself to the two
facts which are evident about them. The first evident fact
(in marked contrast to the delusion of the dancing pagan)--the first
evident fact, I say, is that the pagan virtues, such as justice
and temperance, are the sad virtues, and that the mystical virtues
of faith, hope, and charity are the gay and exuberant virtues.
And the second evident fact, which is even more evident,
is the fact that the pagan virtues are the reasonable virtues,
and that the Christian virtues of faith, hope, and charity are
in their essence as unreasonable as they can be.

As the word "unreasonable" is open to misunderstanding, the matter
may be more accurately put by saying that each one of these Christian
or mystical virtues involves a paradox in its own nature, and that this
is not true of any of the typically pagan or rationalist virtues.
Justice consists in finding out a certain thing due to a certain man
