The results, which you can see in the table below, clearly show that Christians in this country do not, in general, think theologically or care to do so. Of those in this study who claim to be "evangelical," over 50% hold to relativistic beliefs about their own religion and others.
I always thought evangelicals believed that the bible is true. If they do, but also believe other religions are true and valid, then the only conclusion I can come to is that many evangelicals simply do not know what their bibles say.
The implications of this study are immense. We must conclude that there is much poor teaching going on in many evangelical churches. Generally, there must be a serious lack of discipleship within the evangelical church community. Furthermore, the concept of absolute truth seems to have been defeated by ideas of acceptance, tolerance, and the desire not to hurt anyone's feelings.
This study should be a wake-up call to all who care about the church in the USA.
