"A number of scholars... have built on slender foundations what can only be called Thomas romances, such as reflect vividness of their imagination rather than the prudence of historical critics. ... The story of the ancient church of the Thomas Christians is of great significance for the whole history of Christianity in India. It is to be regretted that, when all the evidence has been collected and sifted, much remains uncertain and conjectural. ... Millions of Christians in South India are certain that the founder of their church was none other than the apostle Thomas himself. The historian cannot prove to them that they are mistaken in their belief. He may feel it right to warn them that historical research cannot pronounce on the matter with a confidence equal to that which they entertain by faith."
