The reason I ask is that the ruling on Divine Verdict found here - http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=383163) (7/1/2012 - at the bottom - indicates that by letting the turn go to the declare blockers stage, the creature is considered blocked, even though his creature will die. My creature would survive, but deal no damage (because it was blocked).
It does stop a blocking creature from blocking but that is just because it isn't there to be a blocking creature anymore. The creature it blocked is still considered blocked. The ruling you found indicates that the attacking creatures are still blocked will not deal damage unless they have trample. Conveniently for you, Abyssal Persecutor does have Trample. So, even though it is still blocked, it gets to "trample over" all of its damage to the defending player.
If the situation was with an attacking creature that does not have trample, it would not deal any combat damage at all since it can't trample over and there is no longer a blocking creature around to deal damage to.
