Catholic Evidence Guild
The Catholic Evidence Guild is a loose international association of Roman Catholic lay volunteers which seeks to research and present clear and compelling explanations of the doctrine of the Roman Catholic Church. The organisation was founded in the Diocese of Westminster, England towards the end of 1918. By 1925 there were 20 to 30 branches throughout England. The Westminster branch has spoken regularly at Speakers' Corner since its inception. Prospective speakers were put through a strict training system by the Guild, with the goal of enabling "the ordinary Catholic to explain the truths of his religion in such a way as to reach the understanding of the crowd."
