Book excerpt: Christian theology shaped and is shaping many places in the world, but it was the Greeks who originally gave a philosophic language to Christianity. John Mark Reynolds's book When Athens Met Jerusalem provides students a well-informed introduction to the intellectual underpinnings (Greek, Roman and Christian) of Western civilization and highlights how certain current intellectual trends are now eroding those very foundations. This work makes a powerful contribution to the ongoing faith versus reason debate, showing that these two dimensions of human knowing are not diametrically opposed, but work together under the direction of revelation.
