Two Christian friends are arguing in your small group. Sam says, "Evidence is pointless, because Romans 1 says unbelievers already know God and suppress the truth." Priya replies, "Presuppositionalism is just circular reasoning; we should stick to evidence." In 6-10 sentences, answer both of them and explain how a Reformed apologist can use presuppositional and classical/evidential methods together.Show answer

Both friends hold part of the truth, and this is an in-house debate about method, not about the gospel; Reformed believers such as Van Til and Bahnsen on one side and R. C. Sproul on the other share the same confession. To Sam: Romans 1 does teach that unbelievers know God and suppress that knowledge, but God ordains means as well as ends, and Jesus and Paul both appealed to evidence (Acts 1:3; 17:31). Evidence such as the resurrection or manuscripts, presented as God's own testimony in his world rather than as a hypothesis for a neutral judge, confronts the unbeliever with facts he cannot explain on his own terms. To Priya: every ultimate authority is defended in a way consistent with itself, as the rationalist must use reason to defend reason, so the real question is which starting point can account for logic, morality and science without self-destruction. The course's picture is that presuppositionalism is the foundation and frame, classical and evidential arguments are the rooms we invite people into, cumulative case reasoning shows every room fits one blueprint, and Socratic questions are the front door. In practice, present an argument such as the Kalam or the minimal facts, and when the sceptic escapes by doubting causality, reason or miracles, show that only the Christian God grounds what he is relying on. Throughout, no argument regenerates; we give reasons faithfully and trust the Spirit.

  • Names it an in-house debate (e.g. Van Til/Bahnsen and Sproul) with shared convictions
  • Affirms Rom 1 suppression yet God's use of means and biblical appeals to evidence
  • Answers circularity: every ultimate authority is self-consistent; which circle accounts for the world
  • Shows a concrete way to combine an evidential argument with transcendental reasoning
  • Keeps regeneration as the Spirit's work and a charitable tone
A philosophy student says: "Your cosmological argument fails twice. First, if everything needs a cause, what caused God? Second, even if there is a first cause, that gets you a deist god or an impersonal force, not the Christian God." State the Kalam argument correctly and answer both objections in 6-10 sentences, ending by pointing beyond a generic deity.Show answer

The Kalam does not say everything needs a cause; it says (1) whatever begins to exist has a cause, (2) the universe began to exist, so (3) the universe has a cause. The argument is valid, so the student must reject a premise if he rejects the conclusion. Premise 2 is supported by the impossibility of traversing an infinite past and by evidence such as Big Bang cosmology and the running down of usable energy, though we hold particular scientific models modestly. God, by definition, never began to exist, so asking what caused him misunderstands the argument; something must exist without a beginning, and the question is whether it is a universe that shows signs of starting or an eternal Creator. On the second objection, the student is right that we must not overclaim, but the argument narrows the field: a cause of all space, time and matter must be spaceless, timeless, immaterial and powerful, and personal, because only a free agent can produce a temporal effect from a timeless state. That excludes Zeus, who is part of the world, and an impersonal force. The contingency, fine-tuning and moral arguments add a necessary being, a designing mind and a holy Lawgiver. What these arguments cannot do alone is tell us whether the Creator has spoken; that is why we move to the resurrection, where the Creator identified himself in Jesus Christ (Rom 1:4; Acts 17:31).

  • States the Kalam premises accurately (whatever begins to exist)
  • Supports premise 2 philosophically and scientifically, with modesty
  • Explains why 'what caused God?' misreads the argument
  • Derives the cause's attributes (timeless, immaterial, powerful, personal) and admits the limits
  • Moves to the resurrection and Christ
A colleague says: "The disciples were grieving. They probably had visions of Jesus, and over the decades the stories grew into a legend about an empty tomb." Respond in 6-10 sentences using the minimal facts and the creed of 1 Corinthians 15, and close by explaining what the resurrection means for your colleague.Show answer

A good theory must explain all the facts, not just one. Most scholars who study the subject, including sceptics, accept that Jesus died by crucifixion, that his disciples sincerely believed he appeared to them, that Paul the persecutor and James the sceptical brother were converted, and many accept that the tomb was empty. Grief visions are private experiences, so they cannot explain group appearances to the Twelve and to more than five hundred (1 Cor 15:5-6), nor why Paul, who was hunting Christians, and James, who did not believe, saw Jesus. Jewish expectation would have led grieving disciples to speak of seeing his spirit, not of a bodily resurrection in the middle of history, yet they said they touched him and watched him eat (Luke 24:36-43). The legend theory fails because the creed in 1 Corinthians 15:3-8, with its 'delivered' and 'received' language, is dated by many scholars to within a few years of the crucifixion, and Paul names living witnesses. Visions also leave an empty tomb in Jerusalem unexplained, and the earliest opponents claimed the body was stolen, which assumes it was missing (Matt 28:11-15). If Jesus rose, he is who he claimed: he gave his life as a ransom, bearing the judgement our sins deserve, and was raised for our justification (Rom 4:25). God now commands all people to repent (Acts 17:30), and whoever turns from sin and trusts Christ is forgiven and declared righteous as a free gift.

  • Lists the minimal facts accurately
  • Shows hallucination theory fails (groups, Paul, James, empty tomb, bodily language)
  • Uses the early date of the 1 Cor 15 creed against legend
  • Cites the stolen-body claim as conceding the empty tomb
  • Ends with a clear gospel call: substitution, justification, repent and believe
An atheist friend says: "I'm a good person without God, and when you say I secretly know God exists, that's insulting." Write a gentle presuppositional reply of 6-10 sentences that uses no technical jargon, explains Romans 1 fairly, and shows why objective morality points to God.Show answer

I'd start by agreeing: you are a good person in many ways, and Romans 2:14-15 says God's law is written on every heart, so of course atheists know right from wrong. My question is not whether you can be moral without believing in God, but whether objective morality, right and wrong that are true whether or not anyone agrees, can exist without God. If we are only the product of blind processes, 'torturing children is wrong' becomes a feeling or a survival strategy, yet you and I both treat it as a fact binding on everyone. On Romans 1, Paul is not making a special accusation against atheists; he describes every human being, me included, as knowing God through creation and naturally pushing that knowledge away. That suppression is usually not a conscious lie but a bias we do not notice in ourselves, so I am not calling you dishonest or unintelligent. I am suggesting that your moral seriousness, like your trust in logic, makes most sense if you are made in the image of a holy God. Could we talk about where your sense of right and wrong comes from? And if there is a holy God, the deepest question becomes how people like us, who have all fallen short of his standard, can be forgiven, which is exactly what Jesus came to answer.

  • Affirms the friend's goodness and Rom 2:14-15 (no straw man)
  • Distinguishes being moral from grounding objective morality
  • Explains Rom 1 as true of everyone, suppression as unnoticed bias
  • Asks a genuine question rather than lecturing; no jargon
  • Moves toward the gospel with gentleness and respect (1 Pet 3:15)

Capstone task

Write a 600-word opening statement for a public debate on the question “Does the Christian God exist?” Use a Reformed foundation, at least one transcendental point (logic, morality or induction), at least one theistic argument (Kalam, contingency, fine-tuning or moral), and the historical evidence for the resurrection. Close with a clear, respectful presentation of the gospel.

Hand this in to Mr Scott. He will look for:

  • Presents a clear structure with a thesis and numbered contentions.
  • Uses the transcendental argument accurately and without excessive jargon.
  • States at least one theistic argument in valid form and defends its premises.
  • Presents the minimal facts and rules out at least one natural explanation.
  • Integrates the methods coherently under a Reformed, non-neutral starting point.
  • Ends with the gospel and maintains gentleness and respect throughout.
