I don't understand why Christians, or adherents of any other religion, would have anything against hypnosis. It's simply not true that being hypnotized can make you do anything that's against your beliefs or values. In fact, hypnosis can't make you do anything. The hypnotic state is simply a deeply relaxed state in which your subconscious mind becomes more open to suggestions-- but only suggestions that are in line with what you really want to do and what is right for you. It is a natural state, and if anything, can bring you closer to spiritual reality, not take you away from it.
For example, when I had severe insomnia, a psychologist friend did some work with hypnosis for me. He used the same positive ideas I'd been telling myself, but somehow his soothing, gentle voice and his skill made it easier for me to take in, and that was much more successful than trying to do it on my own.
Whether we are using hypnosis, Paraliminals, EFT, or some other strategy to make positive changes for ourselves, the basic concept (at least as I understand it) is to get past our resistance-- to get out of our own way. Our outer, conscious minds are always coming up with reasons why we can't change or why things can't get better. These are ways to get around our nay-saying.
Best wishes for your practices and your prayers!
