Abstract Boyle distinguished clearly between the areas which we would call scientific and theological. However, he felt that they overlapped seamlessly, and that the truths we discovered (or which were revealed to us) in one of these areas would be relevant to us in the other. In this paper I outline and discuss Boyle's views on the limitations of human knowing, Boyle's arguments in favour of accepting the revelations of the Christian faith, and his views on the kind of epistomological (...) standing that scientific knowledge claims have. Given this background I then consider the relation between hypotheses, theories and facts in Boyle's work, and consider a particular case, that of Boyle's Law, as an exemplification of the claims made in the rest of the paper.
