“…whosoever faileth to embrace the truth of this most great Revelation [the Revelation of Baha’u’llah] will find himself powerless and incapable of establishing the validity of any other cause or creed.” – Baha’u’llah

The above quote implies that internal inconsistencies may be observed by a doubter or a skeptic, even within the Qur’an and the Bible, since rejection of one cause automatically negates another.  This is also a claim of authorship and supremacy of the Revelation of Baha’u’llah.  It should therefore not be surprising that such inconsistencies exist across traditions and books from the perspective of those same skeptics.  And as such differences may be understood with underlying unities, so too can differences across books be understood with a greater unity.
