You mean it's possibly that a few Ted Haggard's could have slipped by with "secret sin" and got cannonized? :)
Yes. (And BTW, that doesn't negate what God has done in any godly man's life. Look at Samson and David. The Holy Spirit came upon Samson at times. Yet he also slept with a prostitute, etc. And David's Bathsheba episode is also obvious. We could all probably agree that God has worked through every saint canonized; but that doesn't mean that all of them steared clear of hell).
