κρυπτός

hidden, secret

Definition

The adjective κρυπτός primarily means 'hidden' or 'secret,' describing things concealed from ordinary view or knowledge. In a literal sense, it refers to physical concealment, such as treasures hidden in a field (Matthew 13:44). More significantly, it describes spiritual realities: actions done in secret, like prayer or giving, which God sees and rewards (Matthew 6:4, 6, 18), and the hidden inner nature of a person that will ultimately be revealed (Luke 8:17). It also points to divine mysteries or truths once concealed but destined to be made known, as in Mark 4:22, where nothing is hidden except to be revealed.

Biblical Usage

Κρυπτός is used 17 times in the New Testament, predominantly in the Synoptic Gospels (Matthew, Mark, Luke). Its usage follows two main patterns. First, it describes private, unseen religious devotion contrasted with public hypocrisy, a key theme in Jesus's Sermon on the Mount (Matthew 6:4-18). Second, it is used in pronouncements about revelation: secrets and hidden things—whether human motives or God's truths—will inevitably be brought to light (Luke 12:2, 1 Corinthians 4:5). This creates a thematic link between ethical conduct and eschatological disclosure.

Etymology

Derived from the verb κρύπτω (kryptō, G2928), meaning 'to hide, conceal, or cover.' It shares a root with words like κρυπτή (kryptē), a hidden vault or cellar, and is the source of the English word 'crypt.' The adjective form denotes the state or quality of being hidden. In the Septuagint (the Greek Old Testament), it often translates Hebrew words for 'secret' or 'hidden place,' carrying this semantic range into New Testament usage.

Semantic Range

This word is theologically significant as it touches on the nature of God, human morality, and eschatology. It underscores God's omniscience—He sees what is done in secret (Matthew 6:6). It also highlights a core Christian ethic: authentic faith is a matter of the heart, not external show. Furthermore, it affirms the ultimate triumph of truth, teaching that all hidden things, both human sin and divine purpose, will be revealed in God's judgment and kingdom (1 Corinthians 4:5). Understanding κρυπτός enriches reading by emphasizing the contrast between human hiddenness and divine revelation.

In the Greco-Roman and Jewish cultural context, 'hiddenness' had significant religious connotations. Jewish piety highly valued sincere, private prayer and almsgiving, in contrast to the public displays of some religious leaders. Jesus's teachings in Matthew 6 directly engage and elevate this value. The concept of hidden mysteries being revealed also resonated in a culture familiar with apocalyptic literature, which dealt with secrets about God, the universe, and the end times.

ἀπόκρυφος (apokryphos, G614) — emphasizes something deliberately stored away or kept secret, often used for hidden writings or treasures. λάθρα (lathra, G2977) — an adverb meaning 'secretly' or 'privately,' describing the manner of an action rather than the state of an object.
