Beware of replacing real truth-based tolerance with spurious professional tolerance. Once upon a time tolerance was the power that kept lovers of competing faiths from killing each other. It was the principle that put freedom above forced conversion. It was rooted in the truth that coerced conviction is no conviction. That is true tolerance. But now the new professional tolerance denies that there are any competing faiths; they only complement each other. It denounces not only the effort to force conversions but also the idea that any conversion may be necessary. It holds the conviction that no religious conviction should claim superiority over another. In this way, peaceful parity among professionals can remain intact, and none need be persecuted for the stumbling block of the cross (Gal. 5:11).3 The aim of this book is to spread a radical, pastoral passion for the supremacy and centrality of the crucified and risen God-Man, Jesus Christ, in every sphere of life and ministry and culture. Increasingly, a ministry under the banner of Christ’s supremacy will be offensive to the impulses of professional clergy who like to be quoted respectably by the local newspaper (John Piper, Brothers, We Are Not Professionals, Kindle location 95).
