Generally, most totalitarian regimes in history have been atheistic, shunning any form of religion and creating a cult of mass worship towards the leader(s) of the government. Does this hold true for the Party in 1984, or does the Party endorse a religion? If so, what religion?
I've done some background research on this, and I've found that Orwell was strongly against anti-Semitism. From Wikipedia:
Writing in early 1945 a long essay titled "Antisemitism in Britain," for the Contemporary Jewish Record, Orwell stated that anti-Semitism was on the increase in Britain, and that it was "irrational and will not yield to arguments." He argued that it would be useful to discover why anti-Semites could "swallow such absurdities on one particular subject while remaining sane on others."
In Nineteen Eighty-Four, written shortly after the war, Orwell portrayed the Party as enlisting anti-Semitic passions against their enemy, Goldstein.
Thus, obviously the Party was anti-Semitic, but what religion does the Party does follow or encourage? I'm looking for answers supported by textual evidence.
