OK guys I have removed the drywall and studs from the interior wall and what I thought was a framed soffit turns out to be 2 2x12's with plywood between them. The beam goes all the way across the living room width just like the center beam of my cathedral ceiling. I have pictures looking up the air return vent which is the end of the beam. I think it's safe to remove the post to make one big opening. Let me know what you think please.
