I'm sorry....did you just say that because Trask REALLY believed persecuting innocent people was the right thing to do, God felt honor bound to assist him? If God were particularly concerned about the likes of Angelique on any given day, don't you think God could have found a more deserving assistant?
I think there's a very good reason why Dan Curtis and the writers NEVER got God involved in their story lines. It's treading dangerous waters.

In the first place, I never made the faintest suggestion that God was assisting Rev. Trask in his persecuting innocent people. I wasn't actually referring to anything he did while he was among the living. Rather, his exorcism was effective because he was asking Divine assistance in his battle with evil.
I don't quite agree with you about the writers never involving God in their storylines. Where you have religion, you have God. Where you have demons, you have the idea of evil personified and the suggestion of a personification of good as their counterpoint.
Dark Shadows often delves into theological themes. The exchange between Nicholas Blair and Rev. Trask was one of them.
