A final volume with a bit of a historical bent is Christian Apologetics Past and Present (Crossway), edited by Willian Edgar and K. Scott Oliphant. Volume I of this two-part anthology recently has been released, covering the years to 1500 A.D. The editors provide helpful introductory material, then present primary source material from writers such as Justin Martyr, Tertullian, Augustine, Anselm, Aquinas and others. Church leaders with an interest in apologetics will appreciate this resource.
