Some things I have learned from my Lutheran Pastor: The book of Acts, which shows the history of the formation of the early Christian Church, by those who knew Jesus personally during his life on earth (with the obvious exception of Paul), is almost all about corporate worship. In addition, the Gospels show Christ spending three years teaching his Disciples how to form and lead the early church as a group entity. How about: "...where two or three are gathered in My Name...."?(Can't find the Biblical citation, right now, sorry)
Biblical Christianity has never been "do-it-yourself". The preached Word is immensely important for Salvation, and you don't get that sitting at home, even from reading your own Bible. "So faith comes from hearing, and hearing through the preaching of Christ" (Romans 10:17). The preached Word has salvific effect above and beyond its cognitive content. You ordinarily need to show up at church to hear it, and, BTW, you also need to take care that you are not listening to a false prophet like Wright.

You were taught well.
