"No One Told You It Was Gonna Be This Way...."

We've got a wide variety of readers here at DRD, so I'm hoping some of you can clear up a mystery for me.

Reformed people think they're on the same team with Lutherans, but Lutherans won't even offer the bread and cup to the Reformed. Anglicans often speak of themselves as non-Protestants more akin to Catholics, but Catholics don't understand themselves to be in communion with Anglicans. And it seems that Lutherans think of themselves as being much more Catholic than Calvinistic/Re-formed, while from the vantage point of Rome we're pretty much a gaggle of individualists.

What gives?
