Christian is an important word. It is not necessarily biblical that we call ourselves Christians (the first followers of Christ weren't called so until the people of Antioch decided to do so ), but I don't think it is worth trying to rename our faith. It seems utterly confusing. Just thinking about all of the possible titles out there is mind-boggling.  That said, I do think having a sort of prefix is helpful to delineate between denominations and branches. An Evangelical-Christian is not a Mainline-Christian; however depending on who they are they may share a lot of similarities. The prefix can somewhat define the culture within the religion.

I do think there is something generation with how we are trying to define ourselves. And I am afraid it is too rapped up in our individualistic culture.We have to find a name that best fits us. It all just seems very "me" focused.

I also, don't think it is proper to try to "not" be like "those other" Christians. I understand why, but for me I still struggle with justifying it. A couple reasons. (1) It makes one seem like they think they are doing it the right way. (2) It shows a great deal of disunity. (3) It assuming that "those other" Christians are a certain way. (4) I think we are to be defining who we are not who we are not.

I also don't think spiritual cuts it. Not just for Christians, but for any faith. Spiritual just seems to generic and broad. What does that mean? Satanic? Muslim? Buddhist? Rastafarian? Atheist (there are some spiritual atheists)? 

It will be interesting if we see Jerry Falwell, American Slave Owners, Martin Luther King Jr. Thomas A' Kempis, Barack Obama, Niebuhr, and Ted Haggard in heaven. I believe some in that group had it more right than others, but ya know they are Christians in the end.
