There's a lot of empowerment and cleaning that must come before that. Even if by some miracle you cause the Kundalini to ascend, without rectifying the soul it will only cause you problems.
Doing the best and the most you can do in a situation like that will pay dividends in later stages when you have more freedom. Progress is progress, but being concerned with Kundalini ascension in this stage is not useful.
Program your aura after feeling the energy buzz to allow yourself the freedom to advance in a safe environment. Something like "I have a safe environment free of Christian influence to advance spiritually."
