In June of the same year Mr Bradlaugh held a debate with Mr Robert Roberts, a leader of a sect called the Christadelphians. He had challenged Mr Bradlaugh to the discussion, and the subject selected was, "Are the Scriptures the Authentic and Reliable Records of Divine Revelation?" The question was to be argued for six nights, two at Leicester and four at Birmingham. After the two nights at Leicester Mr Bradlaugh avowed his disappointment; he had hoped that at any rate the discussion would bring out some new thought, but after two evenings' experience, he doubted whether that result would be attained. "He may be a good preacher," said my father; "he is most certainly not a good disputant." At Leicester the audience were small; at Birmingham they were larger, but the debate does not seem to have been any more enlightening. Mr Roberts was described by one of the Birmingham auditors as "a man of considerable fluency of speech, and overflowing with religious enthusiasm," and also "in all respects a courteous gentleman," but unfortunately those qualities did not make him a debater. On each evening a quarter of an hour was occupied by each disputant in questioning his antagonist according to the Socratic method, and this feature of the proceedings seemed specially to attract the audience, although indeed it must require considerable practice and skill before it can be successfully carried out. Mr Roberts challenged Mr Bradlaugh to further debate, but this the latter felt obliged to respectfully decline on the ground of the challenger's "utter incompetency."
A few days later Mr Bradlaugh was at Liverpool discussing the necessity for disestablishing and disendowing the State Church. His antagonist was Mr William Simpson, the working men's candidate at Liverpool at the general election of 1874. The Concert Hall, Lord Nelson Street, was densely packed, and it was said that there were thousands unable to obtain admission. The arguments were closely followed by those present, and although there was no sort of disturbance, the audience were sufficiently excited to give audible expression to their appreciation or disapproval, and such interruptions were generally met by a sharp repartee from the speaker of the moment.
