What is an overview of perspectives on whether the existence of the Christian God can be established solely through the use of reason and evidence?

Note: I'm interested in the Christian perspective on the question [*Can God's existence be established through reason and publicly accessible evidence?*](https://philosophy.stackexchange.com/q/107660/66156) that I recently asked on Philosophy Stack Exchange. Feel free to read that question and the answers that people have posted for a broader context. --- I am curious to understand the perspectives within the Christian community regarding the use of reason and publicly available evidence to establish the existence of God in general, and the existence of the Christian God specifically. Are there prevailing viewpoints or consensus among Christians on this matter? **What I already know** I'm aware that at least some Christians frequently cite passages like [Romans 1:18-25](https://www.biblegateway.com/passage/?search=Romans+1%3A18-25&version=NKJV) and [Psalm 19:1-3](https://www.biblegateway.com/passage/?search=Psalm+19%3A1-3&version=NKJV) as Biblical expressions of [teleological arguments](https://plato.stanford.edu/entries/teleological-arguments/) for God's existence. This category of arguments has evolved in more contemporary discussions, adopting a renewed shape, notably through an emphasis on the intricate fine-tuning of the fundamental constants in the universe (see [fine-tuned universe](https://en.wikipedia.org/wiki/Teleological_argument#Fine-tuned_universe)) , and an emphasis on the extraordinary complexity and specified information found in living organisms (see [intelligent design movement](https://en.wikipedia.org/wiki/Intelligent_design_movement)) . I'm also aware of the existence of disciplines such as [natural theology](https://en.wikipedia.org/wiki/Natural_theology) and [apologetics](https://en.wikipedia.org/wiki/Apologetics) , which in one way or another attempt to argue for the rationality of the belief in the existence of God and posit that there is sufficient evidence in the natural world to confidently conclude that God must exist. **What I do not know** One aspect that intrigues me, and about which I seek more clarity, pertains to the widespread acceptance or not among Christians of concepts such as natural theology, apologetics, intelligent design, and philosophical/scientific arguments for God's existence that hinge on reason and evidence. Do a majority of Christians align with these disciplines and share the perspective that the existence of God can be established solely through the use of reason and publicly available evidence, in a manner that any reasonable person should be able to study and verify? If there are available statistics on this matter, I would greatly appreciate them, although it's not strictly required to answer this question. As a point of reference, in the realm of philosophy, there are statistics available such as the following: #### God: theism or atheism? |Option|2009|2020|Change|Swing| |-|-:|-:|-:|-:| Accept or lean towards: theism|14.61%|12.5%|-2.11|-1.76| |Accept or lean towards: atheism|72.82%|74.23%|1.41|1.76| |Accept a combination of views|2.47%|0.31%|-2.16| |Accept an alternative view|0.86%|2.78%| 1.92| |The question is too unclear to answer|1.72%|2.01%| 0.29| |There is no fact of the matter|0.54%|0.31%|-0.23| |Insufficiently familiar with the issue|0%|0.15%| 0.15| | |Agnostic/undecided|5.48%|6.94%| 1.46| | |Skipped|0.97%|0.31%| -0.66| | |Other|0.54%|0.46%| -0.08| | N (2020) = 648 N (2009) = 931 (Source: [2020 PhilPapers Survey](https://survey2020.philpeople.org/survey/results/longitudinal)) --- **A case for consideration: Blaise Pascal** Blaise Pascal serves as an illustration of a Christian who contends that the existence of God cannot be conclusively established through reason alone. While his perspective is just one instance, it raises the possibility that others may share a similar viewpoint. > Pascal maintains that we are incapable of knowing whether God exists or not, yet we must “wager” one way or the other. Reason cannot settle which way we should incline, but a consideration of the relevant outcomes supposedly can. Here is the first key passage: > >> “God is, or He is not.” But to which side shall we incline? **Reason can decide nothing here**. There is an infinite chaos which separated us. A game is being played at the extremity of this infinite distance where heads or tails will turn up… Which will you choose then? Let us see. Since you must choose, let us see which interests you least. You have two things to lose, the true and the good; and two things to stake, your reason and your will, your knowledge and your happiness; and your nature has two things to shun, error and misery. Your reason is no more shocked in choosing one rather than the other, since you must of necessity choose… But your happiness? Let us weigh the gain and the loss in wagering that God is… If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation that He is. > > (Source: [Pascal's Wager - Stanford Encyclopedia of Philosophy](https://plato.stanford.edu/entries/pascal-wager/)) --- **Another view for consideration: Reformed Epistemology** Reformed Epistemology is another viewpoint that exemplifies the rejection of evidence and intellectual arguments as necessary requirements for justifying belief in God. > Reformed epistemology is a thesis about the rationality of religious belief. **A central claim made by the reformed epistemologist is that religious belief can be rational without any appeal to evidence or argument**. There are, broadly speaking, two ways that reformed epistemologists support this claim. The first is to argue that there is no way to successfully formulate the charge that religious belief is in some way epistemically defective if it is lacking support by evidence or argument. The second way is to offer a description of what it means for a belief to be rational, and to suggest ways that religious beliefs might in fact be meeting these requirements. This has led reformed epistemologists to explore topics such as when a belief-forming mechanism confers warrant, the rationality of engaging in belief forming practices, and when we have an epistemic duty to revise our beliefs. As such, reformed epistemology offers an alternative to evidentialism (the view that religious belief must be supported by evidence in order to be rational) and fideism (the view that religious belief is not rational, but that we have non-epistemic reasons for believing). > > Reformed epistemology was first clearly articulated in a collection of papers called Faith and Rationality edited by Alvin Plantinga and Nicholas Wolterstorff in 1983. However, the view owes a debt to many other thinkers. > > (Source: [Reformed Epistemology - Internet Encyclopedia of Philosophy](https://iep.utm.edu/ref-epis))
