Sailing under false colors

Let's briefly compare some statements by Peter Enns:

scripture doesn’t line up very well with the conservative paradigm of scripture (some form of inerrancy). That’s why the paradigm needs constant tending and vigilant defending in order to survive.

That happened over 20 years ago, and the memory is still vivid.

I taught at Westminster Theological Seminary (Philadelphia) from 1994-2008.

According to his own timeline, he lost faith in the inerrancy of Scripture before he started teaching at Westminster. He didn't change his mind during his tenure at Westminster.

Which raises an awkward question: did he take the job under false pretenses? It's hard to avoid the inference that he was sailing under false colors the whole time.
