Like Marie and Tom, I would agree that the propriety of "missional" living is in the way it is carried out. My church is heavily focused on missional living, but it's end is to carry the Gospel to the people. Actions such as short and long-term mission trips, community activism, community Bible studies, support for missionaries, and the like, are activities carried out under the banner of missional living.

I think some groups have taken that to mean presenting a watered-down, easy to listen to Gospel. Those ideas are not missional, but rather varieties of the many false-prophets with which we must continue to counter with the Truth.
