I ran into a situation while working at my church and I ran across a sub-panel wired with a 3 wire (#2 seu cable) and all the neutrals and grounds were connected together and bonded to the cabinet. I know a 4 wire should have been ran but was this an acceptable installation prior to 2008? I'm guessing it was done in the late 80's or 90's.

This was never code compliant for a sub-panel within the same structure.
Maybe I'm thinking of the detached structure. What would make the difference on being detached or not?

I believe as long as there wasn't a metallic connection (water pipe) between the two a 3 wire feeder was allowed. I could be wrong.
