We live in a purely physical world. Nothing exists beyond what our senses perceive. No opinion on this issue, but suspicious of such dogmatic claims to knowledge. Humans are the only beings on earth created in the image of God. They are spiritual and material.
People are the product of their culture and only imagine they are self-governing.
Human free will has been drastically diminished by a moral fall from grace, but they are still responsible for the use of their remaining free will. They should depend only on the data of their senses and reason. Rationalism is a myth. Reason is necessary but not sufficient for understanding reality. Reason can disclose truth about reality, but faith and revelation are needed in addition.
