📖 Biblical Definition
Antithesis, in Reformed apologetic usage (Van Til, Bahnsen, Frame), is the conviction that the Christian and non-Christian worldviews are irreducibly opposed at the foundation. The unregenerate man cannot, in his unregenerate condition, neutrally evaluate Christian claims; his fallen reason is bent against God by his own ethical commitment to autonomy ("the carnal mind is enmity against God", Romans 8:7). There is therefore no neutral common ground from which both sides argue. The apologetic task is to expose the unbeliever’s suppression of the truth (Romans 1:18-21) and the internal incoherence of every system built on suppression — challenging the impossibility of the contrary. Antithesis stands behind Van Til’s transcendental method.

Cornelius Van Til's key emphasis. The Reformed doctrine of total depravity extends to the noetic faculties: reason itself is fallen. The unregenerate cannot reason neutrally about God; his rebellion shapes his epistemology.
The household's implication: do not concede neutral ground in apologetic encounters. The unbeliever's claim to neutral reason is itself a position requiring defense, and a position the Bible exposes as untenable.
📖 Key Scripture
Genesis 3:15 — "And I will put enmity between thee and the woman, and between thy seed and her seed."
Romans 8:7 — "Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be."
1 Corinthians 2:14 — "But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned."
2 Corinthians 6:14 — "What fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?"
⚠️ Modern Corruption
Modern Christianity often imagines a neutral middle ground between believer and unbeliever; Scripture and Reformed theology insist on antithesis at the foundation.

Genesis 3:15 establishes the antithesis: enmity between the seed of the woman and the seed of the serpent. The fallen world is not in neutral relation to God; it is in covenant rebellion. The cross is the resolution; the Spirit's regeneration is the saint's entry into the side of life.
The household's apologetic posture is not hostile to people but unsoftened about foundations. The unbeliever is loved; his worldview's foundation is exposed. The two are different things.

Greek antithesis — setting opposite, opposition.
Note: distinct from Hegelian dialectical antithesis (thesis-antithesis-synthesis); the Reformed antithesis is unresolvable except by regeneration.
