Let it be remembered that all churches have persecuted heretics to the
extent of their power. Toleration has increased only when and where the
power of the church has diminished. From Augustine until now the
spirit of the Christians has remained the same. There has been the same
intolerance, the same undying hatred of all who think for themselves,
and the same determination to crush out of the human brain all knowledge
inconsistent with an ignorant creed.
