A theological exploration of a radical shift in Christian thought. This book examines how Christianity adapted to modernity through movements such as the 'Death of God Theology', secularism, and humanism. The traditional notion of "Jehovah" as a tyrannical figure or 'big daddy in the sky' was abandoned as no longer relevant to modern humans in the secular era. The author highlights the transition to a more human-centered form of faith (Christian humanism), where the church was encouraged to engage directly with social, political, and cultural realities, rather than simply focusing on dogmatic rituals. Religion was repositioned as a means of love and concrete action rather than clinging to the fear of hell or divine punishment. This book charts the thinking of reformist theologians of the era who sought to redefine what it means to be a Christian in the modern world.
