To be sure, the doctrine of a personal God interfering with natural events could never be refuted, in the real sense, by science, for this doctrine can always take refuge in those domains in which scientific knowledge has not yet been able to set foot.
The dangers is that every religion, including the Catholic one, says "I have the ultimate truth." Then you start to rely on the priest, the mullah, the rabbi, or whoever, to be responsible for your acts. In fact, you are the only one who is responsible.
Who does not know history's first law to be that an author must not dare to tell anything but the truth? And its second that he must make bold to tell the whole truth? That there must be no suggestion of partiality anywhere in his writings? Nor of malice?
It is only those who are in constant revolt that discover what is true, not the man who conforms, who follows some tradition. It is only when you are constantly inquiring, constantly observing, constantly learning, that you find truth, God, or love.
