arious moral arguments for God’s existence are usually deployed for the purpose of arguing for the truth of God’s existence per se, but they strongly hint at a more specific conclusion. Namely, they are plausibly taken to be evidence that Christianity in particular is true. The claim isn’t that by moral apologetics alone one can somehow deduce
all the aspects of special revelation contained in Christianity, but rather this: in light of Christianity having been revealed, moral arguments for God’s existence point quite naturally in its direction. The following list is far from exhaustive, but offers a few reasons to think this is so.
First, one of the great virtues of moral arguments for God’s existence is that they point not just to the existence of God, but to a God of a particular nature: a God who is morally perfect. A. C. Ewing once said that the source of the moral law is morally perfect. Such a notion is described in various ways: omnibenevolent, impeccable, essentially good, and the like. What does it look like when omnibenevolence takes on human form? Jesus is a powerful answer. Moral apologetics works best when it’s Christological.
Second, to conceive of God as essentially and perfectly loving requires some sort of account. The right account, again, isn’t the sort of idea that we’re able to generate on our own; we depend on special revelation to tell us what it is. But Christianity has provided us with an account of the divine nature that’s Trinitarian in nature. C. S. Lewis wrote in Mere Christianity, “All sorts of people are fond of repeating the Christian statement that ‘God is love’. But they seem not to notice that the words ‘God is love’ have no real meaning unless God contains at least two Persons. Love is something that one person has for another person. If God was a single person, then before the world was made, He was not love.” Moral apologetics works best when it’s Trinitarian.
Third, Christianity has a demonstrated track record historically in reaching people of every race and ethnicity, and every socioeconomic background, and radically transforming their lives. In a book chronicling the spiritual lives of various Christian saints called They Found the Secret can be found this description: “Out of discouragement and defeat they have come into victory. Out of weakness and weariness they have been made strong. Out of ineffectiveness and apparent uselessness they have become efficient and enthusiastic. The pattern seems to be self-centeredness, self-effort, increasing inner dissatisfaction and outer discouragement, a temptation to give it all up because there is no better way, and then finding the Spirit of God to be their strength, their guide, their confidence and companion—in a word, their life.” Moral apologetics works best when it’s individually transformational.
Fourth, Paul Copan speaks of an historical aspect of moral apologetics: the historical role played by Christ and his devoted followers to promote social justice. Morality demands deep cultural transformation too. Copan cites specific cultural developments that can be shown to have flowed from the Jewish-Christian worldview, leading to societies that are “progress-prone rather than progress-resistant,” including such signs of progress as the founding of modern science, poverty-diminishing free markets, equal rights for all before the law, religious liberty, women’s suffrage, human rights initiatives, and the abolition of slavery, widow-burning, and foot-binding.
Jürgen Habermas, who isn’t a Christian himself, writes the following: “Christianity has functioned for the normative self-understanding of modernity as more than just a precursor or a catalyst. Egalitarian universalism, from which sprang the ideas of freedom and a social solidarity, of an autonomous conduct of life and emancipation, the individual morality of conscience, human rights, and democracy, is the direct heir to the Judaic ethic of justice and the Christian ethic of love. This legacy, substantially unchanged, has been the object of continual critical appropriation and reinterpretation. To this day, there is no alternative to it. And in light of current challenges of a postnational constellation, we continue to draw on the substance of this heritage. Everything else is just idle postmodern talk.” Moral apologetics works best when it’s culturally transformative.
Fifth, Christianity holds out the hope for total moral transformation. Morality upholds a standard that all of us fall short of all the time, yet there’s nothing about morality that hints at accommodation or compromise. The right ultimate explanation of morality should be able to make sense of our aspirations for radical moral transformation, and even perfection as something more than a Pollyannaish pipedream. Christianity offers, by God’s grace through faith, moral hope instead of moral despair, forgiveness and liberation from guilt, and the prospect to be totally conformed to the image of Christ, in whom there’s no shadow of turning. The resurrection offers the prescription from both death and sin: abundant and everlasting life. Moral apologetics works best when it is soteriological (offering both forgiveness and transformation, both justification and sanctification).
Sixth, Christianity offers principled reason to think that the glory to come will not just outweigh, but definitely defeat, the worst evils of this world. Christian philosopher Marilyn Adams writes, “If Divine Goodness is infinite, if intimate relation to It is thus incommensurably good for created persons, then we have identified a good big enough to defeat horrors in every case.” Moral apologetics works best when it’s eschatological.
Seventh, Christianity gives compelling reasons to think that every person possesses infinite dignity and value. To be loved by God, the very archetype of all goodness—each of us differently, but all of us infinitely—and to have been made a person in his image is to possess greater worth than we can begin to imagine. And humanity isn’t just valuable in the aggregate, according to Christianity. Rather, each person is unique, each is loved by God, each is someone for whom Jesus suffered and died. And in the book of Revelation, for everyone who accepts God’s overtures of love, a white stone will reveal a unique name for each one of them—marking their distinctive relationship with God and vocation in him. Moral apologetics works best when it’s universal.
The way a labyrinthine maze of jumbled metal filings suddenly stands in symmetrical formation in response to the pull of a magnet, likewise the right organizing story—classical theism and orthodox Christianity—pulls all the moral pieces of evidence into alignment and allows a striking pattern to emerge.
