"It's impossible — no exceptions — for the genuine spiritual or religious impulse to achieve full expression in religions that mandate belief in a supernatural, personal God. There have been genuinely religious Abrahamists, but only because they have somehow maintained the forms of personal God religions, while in fact having abandoned any such belief.
"Some people think that men like St Paul and St Augustine are exemplary instances of what it is to possess the religious temperament. It's easy to see why they have this reputation as long as we stick to the sociological understanding of religion: both were brilliant monsters of egotism, and almost all religious belief, considered as a sociological phenomenon, is about self."
Galen Strawson, British philosopher
