Slavic

What is the whole stuff about slavic in fact? Here follows shortly the
informations I knew about. Which of them are right, which of them are
true?

1)There are today some slavic languages. From these slavic , from the
words which are pan-slavic was reconstructed the "common slavic".The
"common slavic" is kind of Latin for Romnce, the mother of all slavic
languages.
2) The OCS , Old Church Slavic is not common slavic, but a South Slavic
dialect, better said a Bulgarian Dialect.
3) The actual Bulgarian Language did not developed from that dialect
which was presented in OCS but from another one.
4) The dialect of OCS is dead.
5) There are words in OCS who are to find just in the language of
Albanians, Romanians, Aromanians but in no Slavic Language.


P.S. does anyone has a link where one could read some sample of the
oldest OCS text.
