I so wish I had written this. The subject matter is controversial and the author addresses that very point in a powerful, no-holds-barred commentary on Paul’s words in Philippians. Go to Jeff’s blog and learn something really worth knowing.
You need to be warned that this post contains a bad word. But it does so only because the Bible itself contains a bad word. I never knew that. You don't know it either, because you've been protected from knowing it.
It appears in Philippians 3:8 (which I've recently been working on for my 3rd semester Greek class at seminary). Here it is in the original Greek:ἀλλὰ μενοῦνγε καὶ ἡγοῦμαι πάντα ζημίαν εἶναι διὰ τὸ ὑπερέχον τῆς γνώσεως Χριστοῦ Ἰησοῦ τοῦ κυρίου μου, διὃν τὰ πάντα ἐζημιώθην, καὶ ἡγοῦμαι σκύβαλα, ἵνα Χριστὸν κερδήσω...The word you want to keep your eye on is "σκύβαλα"--pronounced "skubala." Here's a literal translation of the verse.
