Can the doctrine of the intercession of the saints be used for self-deception? Yes, it can, and it is, largely. Zion (Church) is made of the unplugged (saints), however, not everyone looking for Morpheus (saint) is looking for the Answer (Jesus) that disconnects. Even in churches where Jesus is the only saint they pray to, many are asking for help only to solve problems in the world (system), never really (wanting to or afraid to, imagining it'd be too hard to cope with?) perceiving its wicked spiritual nature so as to acknowledge the urgent need to get Out of it. That is, they're not looking to become saints themselves.
The Parable of the Ten Virgins teaches us why that is damn dangerous, where we learn that some fools we meet at temples or anywhere else, who call themselves "Christians", are going to realize it is necessary to become wise only when it's too late. You're not safe being a friend of the room, because the greatest trouble is to be found an enemy of God in the end, not to be persecuted by Smith (devil) and all the softwares (logos) hardwired to his system; the hardest word to deal with is, "Verily I say unto you, I know you not", and the most terrible work to be afflicted by is to be cast out by Him from where you've never strived to be.
What do you want from Morpheus and Trinity?
Do not deceive yourself, for they've got only one thing to offer: Sophia.
