Recently there have been in the journals a large number of papers on miracles. The issue debated centred on whether miracles, as violations of natural law by a deity, are possible. Alstair McKinnon, George D. Chryssides and P. S. Wadia contend that the concept of a violation of natural law is defective. Others like Guy Robinson and Malcolm Diamonds claim that the acceptance of miracles constitutes a challenge to scientific autonomy. There have also been defenders of miracles, to name just (...) a few: R. F. Holland, Richard Swinburne and R. C. Wallace. What is, however, overlooked in these polemical discussions is whether theist religions require miracles, and if they do, whether the concept of a miracle required is that of a violation of a law of nature by God. In the present paper I shall argue for an affirmative response to both questions. (shrink)
