Martin Luther to Ulrich Zwingli...
"I would rather drink blood with the pope than mere wine with the Swiss."
I know that Luther believed in it, as do almost all Lutherans. Every Church I can think of that is "directly descended" from Catholicism (Orthodox, Anglican, Lutheran) all believe it. It's the Churches that came from them that do not.
Which Lutherans do not believe it?
As with all Protestant groups, there are a few splinter groups who call themselves "Lutheran" who don't.
As I understood it, I'm LCMS, Lutherans believe that christ is present in communion, but (and this seemed to be confirmed in catholic high school...perhaps my educators didn't know what they were talking about) there's a slight difference between us and the RCC...don't you guys believe that the bread and wine, briefly (if for an extremely small moment) become flesh and blood...I don't really seeing there being a functional difference...Christ is present either way...
