U – Unveiling the Word

Ψυχικός represents a crucial theological concept in New Testament thought, particularly in Pauline literature where it describes the natural, unspiritual state of human existence. The term draws a sharp distinction between what is merely natural or soul-governed and what is spiritual (πνευματικός). In 1 Corinthians, Paul uses this term to explain why unspiritual people cannot understand spiritual truths. The early church used this distinction to elaborate on the transformation that occurs through Christ – from a natural state to a spiritual one. This concept remains relevant today in understanding the fundamental change that occurs in Christian conversion and spiritual growth.
