Only in some sects. Some actually believe they're separate entities, some believe in only God and Jesus, some think they're the exact same being.
If we're counting sects that Christians have killed off (literally, by murder), there is a huge slew of entities discussed, and in quite a number, God the creator is the bad guy using the physical realm to torture souls.
Basically... Abrahamic religions are just as diverse as old mythologies, as much as modern Christians hate that fact.
