The talk of religious tolerance and the mantra “all roads lead to God” is language that has been around for some time and the Christian church today still has to deal with it. I love how J. G. Machen wrote about this around 80 years ago.
“…When I say that a true Christian church is radically intolerant, I mean simply that the church must maintain the high exclusiveness and universality of its message. It presents the gospel of Jesus Christ not merely as one way of salvation, but as the only way. It cannot make common cause with other faiths. It cannot agree not to proselytize. Its appeal is universal and admits of no exceptions. All are lost in sin; none may be saved except by the way set forth in the gospel. Therein lies the offense of the Christian religion, but therein lies also its glory and its power. A Christianity tolerant of other religions is just no Christianity at all (p. 374).
This quote was taken from an article Machen wrote in 1933 called, “The Responsibility of the Church in Our New Age” which is found in Machen’s Shorter Writings.
