Fr. Durrwell, a pioneering preacher of the apostolate's humility and service to the church, confining that, the apostolate has always raised very serious problems for the church, as they touch her very life and present themselves to sharing her own crisis to be theirs. If he, as mostly has tackled, in his book, answers to her very own questions, is because he believes and confesses that God has spoken, and still speaks in Jesus Christ.
