People have died because of either their answer to this question or their refusal to accept another’s answer as truth.
Brian McLaren not only gives insight into this (often contentious) question in his most recent book, Why Did Jesus, Moses, the Buddha, and Mohammed Cross the Road? but has just put up a post about it on his blog. Here’s some of what he writes:
I appreciate logic as much as the next person. But I find your statement seems to be missing some pieces:
“either all religions are false or only one is true.”
I can imagine four options:
1. All religions are completely true.
2. All religions are completely false.
3. One religion is completely true and others are true wherever they agree with it.
4. All religions are partially true and partially false.
I find #1 impossible since different religions contain many contradictions. I find #2 unlikely and incredible. That leaves #3 and #4. A big problem with #3 is that you have to ask, “Whose version of which religion?” For example, if you want to claim Christianity is completely true, you have to ask, “Pope Urban II’s version of Catholicism?” or “Benny Hinn’s version of Pentecostalism?” or “C. S. Lewis’ version of Protestantism?” or “Leo Tolstoy’s version of Russian Orthodoxy?” or … you get the point.
I would be happy to say that God knows what is completely true … but I would reject any human’s claim that they or their religion knows God’s mind with perfect accuracy. That’s why, as a committed follower of Christ, I advocate
– humility of heart and mind,
– a childlike desire to learn,
– love for neighbor, stranger, outcast, and enemy,
– and a sincere hunger and thirst for justice,
because, as Paul said, “we know in part.”
Think on these thing.
