If Anderson is a priest (oh wait... he is!) then even if not explicity stated he will have, in fact, HAD to invoke the name of God to have even been accepted as a priest. Secondly, simply wielding a weapon that was blessed and is now holy means you are receiving Divine Aid. God's power surges through his hand-blades, meaning he will have guidance from the Powers that be above. Even if Vergil is half-demon, he probably only assumes half-demon form in a feeble attempt to retain both physical and nonphysical powers but it's only going to end up hurting him - he's vulnerable both to exorcism (from his demon half) and to holy weapons (from his physical half). Sure, it's effective against someone who refuses to look to God for help, but Anderson not only has God's help, but His empowerment. Either way you look, he's screwed.
