Since it hardly seems fair for me to dominate this post, I only include a few, ok. several quotes from P. Kreeft below. I list the objection that he answers. Please go to the website to see his response to each of these.
Answering Common Objections to the Uniqueness of Christianity
Ronald Knox once quipped that “the study of comparative religions is the best way to become comparatively religious.”
The reason, as G. K. Chesterton says, is that, according to most “scholars” of comparative religion, “Christianity and Buddhism are very much alike, especially Buddhism.”
But any Christian who does apologetics must think about comparative religions because the most popular of all objections against the claims of Christianity today comes from this field. The objection is not that Christianity is not true but that it is not the truth; not that it is a false religion but that it is only a religion. The world is a big place, the objector reasons; “different strokes for different folks”. How insufferably narrow-minded to claim that Christianity is the one true religion! God just has to be more open-minded than that.
This is the single most common objection to the Faith today, for “today” worships not God but equality. It fears being right where others are wrong more than it fears being wrong. It worships democracy and resents the fact that God is an absolute monarch…
Here are twelve of the commonest forms of this objection, the odium of elitism, with answers to each. At website below.
"All religions are the same, deep down."
That is simply factually untrue. No one ever makes this claim unless he is (1) abysmally ignorant of what the different religions of the world actually teach or (2) intellectually irresponsible in understanding these teachings in the vaguest and woolliest way or (3) morally irresponsible in being indifferent to them. The objector’s implicit assumption is that the distinctive teachings of the world’s religions are unimportant, that the essential business of religion is not truth but something else: transformation of consciousness or sharing and caring or culture and comfort or something of that sort — not conversion but conversation. Christianity teaches many things no other religion teaches, and some of them directly contradict those others. If Christianity isn’t true, why be a Christian?
"But the essence of religion is the same at any rate: all religions agree at least in being religious."
"But if you compare the Sermon on the Mount, Buddha's Dhammapada, Lao-tzu's Tao-te-ching, Confucius' Analects, the Bhagavad Gita, the Proverbs of Solomon, and the Dialogues of Plato, you willfind it: a real, profound, and strong agreement."
Yes, but this is ethics, not religion. The objector is assuming that the essence of religion is ethics. It is not. Everyone has an ethic, not everyone has a religion. Tell an atheist that ethics equals religion. He will be rightly insulted, for you would be calling him either religious if he is ethical, or unethical because he is nonreligious. Ethics maybe the first step in religion but it is not the last. As C.S. Lewis says, “The road to the Promised Land runs past Mount Sinai.”
"Speaking of mountains reminds me of my favorite analogy. Many roads lead up the single mountain of religion to God at the top. It is provincial, narrow-minded, and blind to deny the validity of other roads than yours."
Christianity is not a system of man's search for God but a story of God's search for man. True religion is not like a cloud of incense wafting up from special spirits into the nostrils of a waiting God, but like a Father's hand thrust downward to rescue the fallen. Throughout the Bible, man-made religion fails. There is no human way up the mountain, only a divine way down. "No man has seen God at any time. The only begotten Son who is in the bosom of the Father, he has made him known."
"Still, it fosters religious imperialism to insist that your way is the only way. You're on a power trip."
No, we believe it not because we want to, because we are imperialistic, or because we invented it, but because Christ taught it. It isn’t our way, it’s his way, that’s the only way. We’re just being faithful to him and to what he said. The objector’s assumption is that we can make religion whatever we want it to.
"If the one-way doctrine comes from Christ, not from you, then he must have been arrogant."
"Do you want to revive the Inquisition? Don't you value religious tolerance? Do you object to giving other religions equal rights?"
The Inquisition failed to distinguish the heresy from the heretic and tried to eliminate both by force or fire. The objector makes the same mistake in reverse: he refuses to condemn either. The state has no business defining and condemning heresy, of course, but the believer must do it-if not through the Church, then by himself. For to believe x is to condemn non-x as false. If you don’t believe non-x is false, then you don’t really believe x is true.
"I'm surprised at this intolerance. I thought Christianity was the religion of love."
It is. It is also the religion of truth. The objector is separating two divine attributes. We are not. We are “speaking the truth in love”.
"But all God expects of us is sincerity."
"But isn't God unjust to judge the whole world by Christian standards?"
