For centuries, rationalism and scientism have sought to explain human existence. According to their proponents, these schools of thought offer sufficient answers to satisfy humanity's quest to understand reality. However, neither reason nor science can unravel all the mysteries of the human body nor fully answer the deepest questions about the origin, purpose, and destiny of life. As a result, postmodern humanity experiences a profound identity crisis, fragmented between partial answers and existential questions that remain open. Only through faith, through the Holy Scriptures, can we find reliable answers about the constitution of the human being (body, soul, and spirit) and the meaning of existence.
