Critics of Christianity often seize upon specific doctrines or practices they find objectionable: the notion of Hell, theological disputes about Jesus’ death, historical mistreatment of women, young-earth creationism, or even Christian attitudes toward science. These criticisms are not trivial, and many of them point to real shortcomings in the way the faith has been articulated or practiced. Yet, there is a significant oversight in these lines of attack: none of these disputed issues represent the heart of Christianity.
Christianity, despite its myriad denominational divisions and theological disagreements, has always defined itself around a set of core affirmations. These were distilled early on in formulations such as the Nicene Creed: the existence of one Creator God, the historical life, death, and resurrection of Jesus Christ, the reality of the Spirit, and the authority—however interpreted—of Scripture. The diversity of belief within Christianity is wide, but it is framed by this narrow center. What matters most is not uniformity on secondary issues, but shared conviction about these essentials.
Within this framework, certain biblical passages stand out as encapsulating the heart of the faith. John 3:16 is perhaps the most recognizable: “For God so loved the world…”1 It is remarkable that while Christians may argue endlessly about the mechanics of atonement, the meaning of eternal life, or the conditions of belief, no one disputes the verse’s underlying claim about divine motivation: God acts out of love.
This claim—that love is central, not peripheral, to Christianity—is not an incidental flourish. Jesus Himself declared that the entire law and prophets could be summarized in the twofold command to love God and neighbor, extending even to one’s enemies. His disciple John went further: “God is love.” Early Christians absorbed this radically demanding ethic, and outsiders noticed. Pagan observers in the first centuries remarked with astonishment, “See how they love one another.” In an era when disease or misfortune often meant abandonment, Christians became known for caring for the poor, welcoming strangers, and even risking death during plagues in order to nurse the sick. Love was not only their theological claim but their social witness.
Of course, history also tells a darker story. Christians have not always embodied this ethic; indeed, sometimes they have betrayed it. Denominations fracture, politics divides, and love is often obscured beneath power struggles or cultural battles. It is not hard, then, to find ammunition against Christianity in its practice. Yet, these failures, if anything, underscore the point: one does not truly critique Christianity by exposing the lack of love among its adherents. One critiques it only if one challenges the claim that love is its very foundation.
And this is where the conversation becomes most difficult. If love is not only an ideal but the very character of God, then Christianity’s challenge to humanity is not about metaphysical speculation, but about moral motivation. Why should anyone choose to believe in a God defined by love? The answer is not found in proof, for no worldview—religious or secular—rests on indubitable certainty. Rather, the question is existential: if one must choose, why not choose the vision that confronts the selfishness at the root of human brokenness with the one power that transcends it?
Richard Dawkins, in describing the “selfish gene,” articulates starkly the baseline of biological reality: survival is written in the code of our nature, and self-interest governs our being. Christianity does not deny this brokenness but offers a paradoxical answer to it: a call to self-giving love, even to the point of sacrifice. It is precisely this “otherworldly” response that feels so alien to us, accustomed as we are to justifying our self-assertion as mastery of the universe. Christianity dares to claim that the only cure for our this-worldly selfishness is a love that comes from beyond the world itself.
If this is true, then the real challenge for Christianity’s critics is not whether Hell exists or whether creation is young or old. The real challenge is whether love—self-giving, enemy-embracing, sacrificial love—can plausibly be the ultimate ground of reality. For if it can, then Christianity is not merely one option among many; it is the one faith whose very center is what we most desperately lack, yet most deeply need.

Unsurprinsgly, there is no “core” to christianity, since christians can’t even agree on which god to worship. If you can’t agree on what morals your god wants, you do not agree on which god is the right one. You can’t even agree on what “love” means, since your god fails the half-decent definition of love in 1 Corinthians.
And since not one of you can do what jesus promises to his true followers, per your own bible, you are all frauds.
” Rather, the question is existential: if one must choose, why not choose the vision that confronts the selfishness at the root of human brokenness with the one power that transcends it?”
Pascal’s wager, nothing more and since Christanity doesn’t do this, your appeal fails rather miserably. Happily, humans aren’t “broken” and that is a lie all cults use to scare people into the cult.
Not sure what you mean by “Christianity doesn’t do this” with respect to Pascal’s wager. It seems that one of the arguments of this blog is that, because of the uncertainty that still exists in our metaphysics, something like Pascal’s wager is really all anyone has. But you apparently disagree, so help me understand what you see as the difference between Pascal’s wager and the uncertainty that I’ve tried to describe.
Christianity doesn’t address the “selfishness at the root of human brokenness”. Christianity is an amazingly selfish religion with the cult’s leader saying abandon everything for the cult. Unsurprisngly, every cult tries to convince people they are “broken” and need the cult. Happily, we don’t.
No such thing as “metaphysics”, and since you have no evidence for your god or any gods, no reason to think making pascal’s wager achieves anything at all.
Ok, thanks. I think I understand now. You might check out the following post, as it touches on another aspect of Pascal’s Wager – curious what you think.
Obviously, we differ on things like the definitions of “evidence” and “metaphysics”. I like to think that I’ve aligned with most subject matter experts, but these days it’s easy to find subject matter “experts” that support whatever view one wants.
