Justified True Belief

Intro Hard-Classical vs. Soft-Classical: In the broader classical tradition, there is a "hard" and a "soft" version of the method. Hard-Classical apologetics typically insists that sound arguments from natural theology and historical evidence are epistemically necessary for rational Christian belief. On that stricter view, a person would not be fully justified in believing that Christianity is true unless (at least implicitly) they rely on a successful chain of reasoning that first establishes theism and then, on that basis, the truth of Christianity (e.g., by arguing from fulfilled prophecy or from the resurrection as a divine confirmation of Jesus’ claims). The classical "two-step" (God-then-Christ) is not just a helpful evangelistic strategy, but the basic route by which Christian faith is shown to be rational at all.

Soft-Classical apologetics, by contrast, keeps the same formal structure of the two-step method but adopts a very different epistemology. Following Reformed Epistemology and Scripture’s teaching about the Holy Spirit, soft-classical apologists (like William Lane Craig) deny that arguments are necessary for rational faith. A Christian can know the gospel is true through the self-authenticating witness of the Holy Spirit, which provides a properly basic warrant for belief in God and in Christ. Natural theology and historical evidences are still central for showing Christianity to be true to others and for answering objections...but they are not the ultimate ground of the believer’s assurance.

(P1) The Christian’s fundamental knowledge that Christianity is true is grounded in the self-authenticating witness of the Holy Spirit, not in argument or evidence. + The believer’s assurance that the gospel is true is immediate and non‑inferential. The Spirit testifies to the truth of Christ and Scripture in such a way that this testimony can be properly basic...warranted apart from prior argumentation. Arguments and evidences can confirm and support this knowledge, but they are not its foundation. Even if a believer cannot answer all objections, the Spirit’s witness can function as an intrinsic "defeater‑defeater," preserving the rationality of faith in the face of counterarguments.

(P2) To show Christianity is true, the classical method first uses natural theology to establish the existence of God, and then uses historical evidence (eg...for Jesus’ resurrection) to identify as the God of Christianity.

(C1) Therefore, Christians can rationally know Christianity is true apart from arguments, while still having a robust, public case that shows Christianity is true to others. + The soft‑classical view claims to secure both sides: the ordinary believer’s assurance does not hang on the shifting philosophical or historical debates, and yet Christianity can still be commended as objectively reasonable through a structured, two‑step apologetic that moves from God to Christ.

(P3) Arguments and evidence are not strictly necessary for rational Christian belief, but they are important for removing obstacles, commending the faith, and confirming the believer’s confidence. + Because the Spirit’s witness is sufficient for rational faith, even those with limited education or no exposure to formal apologetics can still know the gospel is true. Nevertheless, classical apologetics assigns a crucial role to arguments: they clarify, defend, and commend the faith; they remove intellectual stumbling blocks; and they can strengthen believers when they face doubts or challenges. The Spirit ordinarily uses such means as part of his work.

(C2) Therefore, soft-classical apologetics claims to provide (1) a secure, Spirit-grounded basis for Christian knowledge, and (2) a rational, two-step public case that establishes Christian theism as the most plausible worldview.

+ Evidentialist: Craig’s knowing/showing distinction and priority of the Spirit’s witness blurs the practical necessity of evidence, and risks undercutting the central evidential role of the resurrection.

1. Scripture itself grounds assurance in the Spirit as well as in historical facts. The New Testament both stakes everything on the resurrection (1 Cor 15:14–19) and emphasizes the Spirit’s inner testimony (Rom 8:15–16; 1 Jn 5:6–10). A robust theology of knowledge must honor both strands. Craig’s knowing/showing distinction is an attempt to systematize this biblical balance: the Spirit gives believers immediate assurance, while the resurrection provides the central public evidence God intended. 2. Saying the Spirit’s witness is sufficient does not make evidence optional. "Sufficient" is not the same as "exclusive." The fact that the Spirit can warrant belief apart from evidence does not mean Christians should neglect the evidence God has graciously provided. On the contrary, the New Testament apostles constantly appeal to the resurrection as God’s public vindication of Jesus. Craig explicitly affirms that arguments and evidence are crucial for evangelism, for bolstering believers, and for obeying 1 Peter 3:15. 3. The apologetic task is not the same as the basis of an individual’s assurance. It is one thing to ask, "What must be true for a believer to be warranted in his faith?" and another to ask, "What should we present to a skeptic?" Craig’s answer to the first is "the Spirit’s self‑authenticating witness"; his answer to the second prominently includes "the historical evidence for the resurrection." This is not a contradiction but a distinction between two different questions. 4. Far from undercutting evidence, the soft-classical model motivates rigorous historical work. Precisely because Craig believes God uses means, he sees historical apologetics as one of the principal instruments the Spirit employs to draw unbelievers to himself. That is why so much of his own work is devoted to defending the resurrection evidentially. The category of "knowing" by the Spirit protects believers from skepticism; the category of "showing" by evidence energizes the apologetic enterprise.

+ Evidentialist: If competing religions also claim a self-authenticating inner witness, you can’t fairly privilege your Spirit-witness over historical evidence without begging the question.

1. First-person warrant is not neutralized by the existence of rival claims. That others report analogous experiences does not, by itself, defeat a Christian’s properly basic belief. If Christian theism is in fact true, then the Spirit’s witness is a truth‑connection to reality, and it is rational to trust it even in a pluralistic environment. Symmetry of claims does not entail symmetry of truth or warrant. 2. Public evidence is precisely where the symmetry between rival claims is broken. Here Craig aligns with the evidentialist impulse: Christianity is uniquely supported by a historically credible resurrection. His point is not that Christians can dispense with that evidence, but that the believer’s own warrant does not depend on having worked through it. In apologetics, the historical case is brought to the table to challenge rival religious narratives and to show that the Christian claim is uniquely well grounded. 3. Inner testimony and public evidence are coordinated, not competitors. On Craig’s view, the Spirit may use the very historical evidence for the resurrection to draw someone to faith; then, once that person believes, the Spirit’s internal witness becomes the ultimate ground of assurance. Thus, the order of psychological coming‑to‑faith may begin with evidence, while the order of epistemic priority in the mature believer locates the deepest ground of knowledge in the Spirit. 4. Appealing to the Spirit is not question-begging; it is a theologically informed epistemology. If Christian theism is even possibly true, it is reasonable to ask what cognitive situation one would expect if God exists and wants to be known. The idea that God would give an internal, self‑authenticating witness is not ad hoc; it arises naturally from Christian theology. That theology then shapes how Christians interpret both their experiences and the historical evidence.

+ Presuppositionalist: Craig’s two-step method assumes too much neutral common ground and does not take the noetic effects of sin, or Scripture’s authority, as seriously as it should.

1. The soft-classical method does not presuppose a religiously neutral standpoint. Craig fully affirms the noetic effects of sin and the biblical teaching that unbelievers suppress the truth (Rom 1:18–21). When he appeals to "common ground," he is not claiming metaphysical or spiritual neutrality, but rather that God’s general revelation is sufficiently clear that even fallen image‑bearers can recognize certain truths when confronted with them and that the Spirit can use arguments to pierce their suppression. 2. Appealing to shared rational principles is itself a use of God-given revelation. On Craig’s account, logic, moral awareness, and the orderliness of the world are all aspects of general revelation. When he argues from these features of reality to God, he is not exalting autonomous reason over Scripture; he is calling attention to what God has already made known. This is why Paul can reason from creation and conscience in Romans 1–2, and from history and miracle in Acts 17, without first demanding explicit acceptance of biblical authority. 3. Scripture’s authority is central in Craig’s theology, even if not always his starting point in argument. In theology properly so called, Scripture is for Craig the norma normans, the ultimate norm. In apologetics, however, his immediate task is often to persuade someone who does not yet recognize Scripture as God’s Word. For that task, he uses common‑ground arguments that can be appreciated by believer and unbeliever alike, with the expectation that, once convinced, the person will bow to Scripture’s authority. 4. Presuppositional insights can be incorporated without abandoning the two-step structure. Craig agrees with presuppositionalists that the triune God is the ultimate ground of logic, morality, and nature, and that unbelief involves culpable suppression. His classical structure simply orders the arguments in a way he finds persuasively powerful. Recognizing sin’s effects on reason motivates prayer and dependence on the Spirit; it does not preclude the use of arguments that appeal to general revelation.

+ Presuppositionalist: Classical 'God-then-Christ' reasoning can actually obscure the distinctly Christian God, since bare theism is not the God of Scripture.

1. The "God" of natural theology, as Craig uses it, is not meant to be religiously neutral. Properly developed, arguments from cosmology, morality, and rationality yield a personal, transcendent, morally perfect Creator. That profile already excludes many non‑Christian options (e.g., finite gods, impersonal ultimate realities). While it does not yet specify the Trinity, it significantly narrows the field of live candidates in the direction of biblical theism. 2. The two‑step order is logical and pedagogical, not theological rank-ordering. Craig is not claiming that a generic deity is more "fundamental" than the triune God. Rather, he maintains that in argument it is often helpful first to establish that some God exists, and then to ask which revelation best identifies that God. Theologically, on Craig’s view, the God whom natural theology discovers is the Christian God; historically and experientially, people often come to recognize his fuller identity step by step. 3. The New Testament itself sometimes argues in a staged way. Craig points to Paul in Acts 17, who first argues with Athenians from creation and providence to a Creator‑Judge, and only then introduces Jesus and the resurrection. This does not imply belief in a "neutral" God distinct from the God of Scripture; it illustrates a flexible, contextual strategy that moves from what the audience already grants to the full gospel claim. 4. A multi-stage case need not produce compartmentalized reasoning. On Craig’s approach, good teaching can make it clear that the same triune God underlies every stage of the argument and that general and special revelation are two modes of disclosure from the same Lord. The two-step structure is a matter of argumentative order, not of dividing reality into unrelated compartments.

+ Reformed Epistemologist: Craig still gives arguments and evidence too central a role; his epistemology is not consistently Reformed but drifts toward evidentialism in practice.

1. The basic soft-classical structure is explicitly Reformed: properly basic belief grounded in the Spirit. Craig wholeheartedly adopts the Reformed Epistemology insight that belief in God...and even specific Christian beliefs...can be properly basic, warranted by the Spirit’s work apart from argument. That is precisely why he insists that the believer’s knowledge does not stand or fall with the success of any particular apologetic argument. 2. Emphasizing the usefulness of arguments does not deny their non-necessity. There is a difference between saying "arguments are required for rationality" (which Craig rejects) and saying "arguments are highly valuable for the church’s mission" (which he affirms). His own practice of doing apologetics at a high academic level reflects pastoral and evangelistic concern, not a belief that faith is epistemically defective without such arguments. 3. Ordinary believers are not second-class for lacking formal apologetics. On Craig’s view, precisely because the Spirit grounds their belief, a simple Christian with no philosophical training can be as fully warranted in faith as the most sophisticated theologian. His insistence on the value of apologetic arguments is directed at those called to that kind of ministry and at contexts where objections are pressing, not at creating an intellectual hierarchy of "real" Christians. 4. Reformed Epistemology and classical apologetics can be integrated. Craig sees Reformed Epistemology as explaining how belief in God can be rational without argument, and classical apologetics as explaining how Christians can commend that same belief in the arena of public reason. He takes the soft‑classical view to be precisely this integration, not a retreat back into evidentialism.

+ Reformed Epistemologist: Craig’s talk of the Spirit as an 'intrinsic defeater-defeater' risks making his position unfalsifiable and epistemically insulated.

1. Intrinsic defeater-defeaters do not eliminate all possible defeaters. In Plantinga’s sense, an intrinsic defeater‑defeater is a kind of warrant that can rationally override certain kinds of putative defeaters. Craig’s claim is not that Christians should never re‑examine their beliefs or that no evidence could ever shake them. Rather, if Christian theism is true, the Spirit can provide such strong assurance that many objections will simply not rationally overturn a believer’s faith. 2. This is not epistemic arrogance but theological realism. If God really exists and really indwells believers, it is not surprising that he can give them an assurance that remains rational even in the face of unanswered puzzles. Craig uses the familiar analogy of an innocent person who remembers clearly that he did not commit a crime and may rationally maintain his innocence even in the face of perplexing circumstantial evidence. That is not dogmatism; it is proper weight given to a strong source of warrant. 3. The soft-classical view still makes room for serious intellectual struggle and growth. Craig does not suggest that Christians should ignore evidence or never wrestle with difficult objections. On the contrary, his entire apologetic ministry assumes that such wrestling is important. The doctrine of the Spirit as an intrinsic defeater‑defeater is intended to protect believers from crippling skepticism, not to excuse intellectual laziness. 4. Reformed Epistemology itself recognizes strong basic beliefs. Reformed Epistemology does not treat all beliefs as equally vulnerable. Some properly basic beliefs can be very deeply warranted. Craig’s proposal is that, for the Christian, the Spirit’s witness to the truth of the gospel is of that sort. He presents this as a development within the Reformed tradition, not a departure from it.
