Define 'God'. Define 'exist'. Christianity says 'God' is 'Love' (Compassion). does Love exist? Is Compassion a person? There's a lot of mental chicanery to interpret one thing as another here. I believe that Christianity and Buddhism tell us that what the ancients were taught to think of as some all-powerful external Being, we should understand to be our common humanity and deepest experience of what all material forms merely express.
