I think you misread. He wrote christian values. No importance of being christian to accept the basic values. Treat your neighbor as you would like to be treated by them. When someone pushes you to walk a mile with their luggage. Offer them to carry it two miles. Use your talent and be brave. Do not be afraid to fail. Practice forgiveness and be greatful for the life you get. Care about voulnerable people. With those values teached from christian religion in particular, but told in many other religions as well, societies can thrive.
