One of Christianity Today’s “100 Most Influential Books of the 20th Century”, J. Gresham Machen’s earnest case for true, biblical faith and communion in Jesus Christ has been read around the world for 100 years. Originally published in 1923, this new edition features a brand-new foreword by Kevin DeYoung and is issued with the hope and prayer that the next century will be celebrated as one of reformation and renewal for Christ’s church throughout the world.
