In Philippians chapter 3, our apostle Paul lists several things that he used to think were important but that he now considers to be "garbage." One of these things is, "...in relation to the righteousness which is in law, becoming blameless" (Philippians 3:6). Paul's quest for blamelessness (that is, sinlessness) used to consume his every waking moment as a Pharisee. But once the man learned of Christ, he considered this quest to have been empty and stupid. And yet Paul (as Saul the Pharisee) came closer to moral perfection (in relation to the righteousness which is in law) than anyone. 

If this is true—which it undoubtedly is, anyone can read it—then why are Christians still straining to become blameless in relation to the righteousness of law? The answer is right in the context, in verse eight of Philippians 3: "But, to be sure, I am also deeming all to be a forfeit because of the superiority of the knowledge of Christ Jesus, my Lord." Religionist especially (and ironically) Christians—have no knowledge of Christ.

And finally, what does Paul call people who still vigorously promote any attempt to become blameless in relation to the righteousness which is in law? He calls them "evil workers" (Philippians 3:2). I wish more critics of the Christian religion would use this nomination against modern pastors and priests.
