'However, we must not only beware of all that is
obvious and unmistakable, but also of all that can deceive by fraud and
cunning. What could be more clever and cunning than the Enemy's moves
after being unmasked and worsted by Christ's coming? Light had come to
the gentiles and the lamp of salvation was shining for the deliverance
of mankind, so that the deaf began to hearken to the Spirit's call of
grace, the blind to open their eyes upon the Lord, the sick to recover
their health unto eternity, the lame to make speed to the Church, and
the dumb to raise their voice aloud in prayer. Thereupon the Enemy,
seeing his idols abandoned and his temples and haunts deserted by the
ever growing numbers of the faithful, devised a fresh deceit, using the
Christian name itself to mislead the unwary. He invented heresies and
schisms so as to undermine the faith, to corrupt the truth, to sunder
our unity.'
