As far as spirituality and theology go I too agree that they are not even legitimate fields of study since they are not based on observation,experimentation, or objective evidence.When it comes to christianity if you take away thier bible they have nothing from which to argue their stance from.Their whole belief system is based on belief in the myths in their so called holy writ and their psycho-emotional responses to those myths.The so called "feeling" of the presence of God is all in the mind in my opinion and can be influenced by many psychological factors.
There is nothing people will not maintain when they are slaves to superstition
