Here's a teaser:
Gnostic Myth # 1: Christianity isn’t a Religion, it’s a Relationship
By relocating the nexus of religion in the private experience of each individual and self-consciously downplaying the public and corporate aspects connoted by the word “religion”, much of contemporary evangelicalism has unknowingly drunk deeply from the wells of Gnosticism. In the process, much of the modern church has lost the categories with which to think about Christendom, viewing the faith primarily through an individualistic lens.
Those interested in exploring this aspect further should consult the first essay in Stephen Perks’ Common-Law Wives and Concubines.
Gnostic Myth # 2: Salvation Means Going to Heaven When You Die
For much of the contemporary evangelical community, the doctrine of bodily resurrection of believers has been eclipsed by the innovation that salvation means living in heaven for eternity. It is revealing that many evangelicals find nothing amiss with the idea that the immortality of the soul, not the resurrection of the body, is the goal of personal salvation. Moreover, recent surveys have shown that many Christians no longer believe that their bodies will be resurrected at all.
Those interested in exploring this further should continue reading this paper or consult N.T. Wright’s book Surprised by Hope or my blog post "Resurrection or Disembodiment? Gnosticism in Evangelical Theology."
Gnostic Myth # 3: The Material World isn’t Important
Under the influence of Gnostic myth # 2, as well as various eschatologies which teach a lack of organic continuity between what happens during this age and the future renewal, many Christians have colluded with the Gnostic notion that what happens in this world is unimportant to God.
Those interested in exploring this aspect further would do well to consult Os Guinness’ Fit Bodies Fat Minds or my article "Recovering the Protestant Affirmation of Life."
Gnostic Myth # 4: Institutional Religion is Bad
Having been suckered into embracing a number of Gnostic dualisms, many modern Christians automatically think that institutional religion is at odds with genuine heart-felt faith, and that whatever we give to the former is less we have for the latter.
Those interested in exploring this aspect further should consult DeYoung and Kluck's Why We Love the Church: In Praise of Institutions and Organized Religion and my article ‘Institutional Religion.'
