The stained-glass barrier which Mr. Womack feels must be crashed is the wall of isolation with which the Christian churches have surrounded themselves. But it is not the world that Womack wants to let in; it is the church that he wishes to let out so that it may proselytize the heathen nations. Basing his suggestion on the Acts and the Epistles, he proposes an apostolic program for this evangelical action: the formation of strong nuclei of believers, the propagation of the faith ""as an issue"" through the mass media supplemented by the example of apostolic Christian congregations, increased emphasis on the missionary function of the church, etc. Missionary activity is not a popular term among the ""establishment"" churches today. But to so-called evangelical and fundamentalist churches, however, it is equivalent to militant Christianity; and, for such churches, Womack's work will prove to be not only a call to spiritual arms, but an effective and exegetically sound program of action.
