Some people believe that belonging to a local church,
temple, mosque or synagogue will get them to Heaven.

No one thinks that going to a synagogue will get them into heaven, since
anyone going to a synagogue knows there is no heaven.

So what's the point of going to a synagogue then? AAMOF, why profess any
faith at all if there is no heaven?

One goes to synagogue for communal prayer. One professes a faith because it
helps them lead a morally correct life. Both are optional aids to leading a
morally correct life.
If believing in heaven works for you, then it is what you should believe;
all paths are equally good. (You won't be dissappointed. (no opportunity to
be))


Appears the Sadduccee sect won -- at least in the version of Judaism you
are discussing.

No reference in the Bible to heaven or any sort of life after death in the
Bible. (er, Torah) Well, there is that one story where King Saul consults
with spirits, but he was mad at the time.
