over contextualising Acts 17

Paul's sermon to the Athenians is frequently used as the paradigm for contextualising the Gospel and as the contextualised sermon. in the past I have preached the passage this way, and I do think that there is much we can learn from here on how to communicate the Gospel to people. But don't you think, we've stretched the point too far? I mean, when we actually read Paul's address we discover that there is much which is counter-cultural and which outrightly rejects the Athenian way of life and view of reality.

Perhaps it's more of the, let's start with what you understand and then blow it up and then replace it with the Gospel approach!
