From the beginning the followers of all religions
have believed in two seas, -- one salt and one
fresh; in two trees -- the tree of good and the tree
of evil. For this men have called one another
heretics. Misinterpreting the divine commands,
men have acquired prejudices and on these
prejudices they have waged religious wars and
caused bloodshed. Behold what is happening to-day!
Men are killing their brothers, believing this to be
the cause of salvation, believing that such work
is approved by God, believing that those whom
they kill will be sent to hell.

Baha'u'llah speaks to humanity in a different tone,
declaring humanity to be like the leaves of a single
branch, the branches of a single trunk.
