It's likely. The same happens in Adamant when the Inquisitor and Co. face certain death as they fall from the bridge. I have no problem in having faith. When people asked me if I believed in the Maker, I said that I didn't know. I can't prove him, neither I can disprove him. I understand when Blackwall says that in the end, it doesn't matter if Andraste was involved or not, what matters is that the common people need to believe in something, otherwise they will just fall in despair. But it just bothers me greatly, when people are shown that something happened in an certain way, and yet, they insist in the wrong theory. I just cannot accept religious belief being used as an excuse to ignore the cold hard facts.
I don't think anyone, in the fanbase at least, is ignoring facts.
Andraste didn't meet you in the Fade, touched your hand and gave you the Mark. Fact.
Then again, there was a god in Corypheus' corner, even if he did act through mundane means (here's a ball, go nuts), so who's to say there wasn't one in the Inquisitor's?
The Mark didn't activate automatically in Adamant. The Inquisitor, being more experienced, did it himself/herself and they just fell into it as gravity dictates. Not sure if the same could have happened at Haven. I assume the explosion we see blasting Corypheus back was what destroyed the Temple. Corypheus survived because he is immortal and it is conceivable the Mark would protect the Inquisitor but the Divine?
Or something else entirely happened. The vision isn't clear after the Inquisitor grabs the orb and Corypheus attempts to attack.
