Something Protestants don't admit

One thing that Reformation era type Protestants don't recognize or don't admit is how mystical we are compared to the other branches. I mean we spiritualize the church, and we spiritualize the sacraments. I do it to more of an extreme, but all historic, classical Protestants do it to some degree. I think, obviously, that it's legitimate, because for such Protestants regeneration is the main thing. Regeneration by the word and the Spirit.
