That which God hath ordained as the sovereign remedy and
mightiest instrument for the healing of the world is the union of all its
peoples in one universal Cause, one common Faith. This can in no wise be
achieved except through the power of a skilled, an all-powerful, and inspired
Physician. By My life! This is the truth, and all else naught but error.
- Baha’u’llah (‘Epistle to the Son of the Wolf’)
