What is needed is a metamorphosis of thinking - a qualitative change in the form of thinking.
Because modern thinking is intrinsically incoherent, pathological and anti-Christian: we really must change it.
Modern Man has tried and tried to believe in Christianity while thinking like a nihilist... it doesn't work. The dead materialism of the thinking weakens, erodes and subverts the belief.
But specifically (and aside from its fundamentally anti-Christian structure and assumptions and implications) why must we change our thinking?
What are the reasons, and what are the implications?
