What better way to start things off than with a quote from the Modernist heresiarch himself:
Thus man's religious idea is first felt as a vague need of adjusting his action to that whole of which all but a little part is hidden from him; of coming to terms with an invisible and mysterious world. This "idea" is the soul of the lowest and of the highest forms of religion.
(George Tyrrell, Christianity at the Crossroads, ch. IX)
