Paul uses anthropinos in 1 Corinthians 2:13 to contrast Spirit-taught wisdom with human wisdom: "not in words taught by human wisdom but taught by the Spirit." In Romans 6:19 he says "I am speaking in human terms, because of your natural limitations" — acknowledging the limits of human analogy when speaking of divine things. The word underscores Scripture's consistent theme: human standards and human wisdom, while real, are insufficient to grasp divine realities. Only revelation bridges the gap.
Anthropinos means "of or belonging to man" — human, human in character, measured by human standards. It contrasts the merely human with the divine, the natural with the spiritual.
