Another philosophy  that    developed   in  response    to  the Era of  Warring States  was Daoism. Its founder
was Lao-zi  (or Lao-tsu),   who is  believed    to  have    lived   during  the fifth   century BCE.    The philosophy
adapted traditional Chinese concepts    of  balance in  nature, or  yin (female,    submissive) and yang
(male,  assertive). According   to  Daoist  philosophy, human   understanding   comes   from    following   “The
Way,”   a   life    force   which   exists  in  nature.
In  contrast    to  the Confucian   respect for education   and for orderly government, Daoism  taught  that
political   involvement and education   were    unnecessary.    Rather, in  time,   the natural balance of  the
universe    would   resolve most    problems.   Chinese thought and practice    gradually   blended both
Confucianism    and Daoism  to  include a   concern for responsibility  for the community   and time    for
personal    reflection.
Judaism
Unlike  other   religions   of  the period, notably Buddhism    and Christianity,   Judaism was not a
missionary  religion.   Although    the Jews    had lived   in  Babylon for 70  years,  with    some    Jews    remaining
after   most    of  the former  captives    returned    to  Babylon,    they    did little  to  attempt to  convert non-Jews.
From    the Jewish  faith,  however,    would   come    another major   world   religion:   Christianity.
Christianity
A   key element of  Judaism was the belief  that    God had promised    to  send    the Jews    a   Messiah ,   or  a
savior  from    their   sins.   Some    of  the early   Jews    felt    that    that    promise was fulfilled   when    Jesus   was born
in  the Roman   province    of  Judea   about   4   to  6   BCE.    As  an  adult,  Jesus   and his 12  disciples   ,   or
followers,  went    throughout  the land    of  Judea,  preaching   the forgiveness of  sins.   Jesus   was also    called
Christ, meaning “anointed.” When    Jesus’  teachings   were    feared  as  a   threat  to  Roman   and Jewish
authority,  he  was tried   and put to  death   by  crucifixion.
The network of  Roman   roads   facilitated the spread  of  Christianity    throughout  the empire.
Missionaries,   traders,    and other   travelers   carried the Christian   message of  forgiveness of  sins    and an
afterlife   in  heaven  for those   who believed    in  Jesus   as  their   savior  from    sin.    The greatest    missionary
of  the early   Christian   church  was Paul    of  Tarsus. A   Roman   citizen,    he  undertook   three   missionary
journeys    throughout  the Roman   Empire  in  the first   century CE. Accounts    of  Jesus’  life    in  addition    to
the missionary  efforts of  Paul    and other   followers   of  Jesus   are found   in  the New Testament of    the
Christian   Bible.
Several Roman   emperors    considered  Christianity    a   threat  to  their   rule.   Although    some,   such    as
Diocletian, persecuted  the Christian   church, it  continued   to  grow.   In  313,    the Roman   Emperor
Constantine changed the position    of  earlier Roman   emperors    regarding   Christianity.   In  the Edict   of
Milan he    permitted   the practice    of  Christianity    in  the Roman   Empire. Christianity    became  the official
religion    of  the Roman   Empire  in  381 under   Emperor Theodosius.
After   its adoption    as  the state   church  of  Rome,   Christianity    in  the West    began   developing  an
organization    under   the leadership  of  the bishop  of  Rome,   or  pope    .   In  addition    to  priests who served
local   churches,   monks   and nuns    withdrew    from    society to  devote  their   time    to  prayer  and meditation.
As  it  spread  throughout  the Roman   world,  Christianity    gained  popularity  because of  its appeal  to  all
social  classes,    especially  the poor.   Women   received    new status  as  Christianity    taught  that    men and
women   were    equal   in  matters of  faith.  After   the fall    of  the Western Roman   Empire, Christianity
spread  to  northern    Europe, the Balkans,    and Russia.
