Successful and faithful?

We have found a fine ELCA congregation. Yet its success seems to be a result of being popular and trendy, while sacrificing Lutheran teachings. There are no announcements of the real presence of Christ in communion. When I asked about this I was told, "We have too many former Baptists at our services. If we are strict about Luther's beliefs we will offend them. What do you think?

As a lifelong Lutheran I'm uncomfortable answering the question, "Are you saved?" Could you give me some conversational lines that I can use with fundamentalist friends?
