I have recently been reading "Miracles" by Craig Keener and it is a very interesting book. However, it has got me thinking, how do others understand the occurrence of contemporary miracles in traditions different from their own. In the book, based on the results from a Pew survey of the US and the "Global South" it was estimated that some 200 million Pentecostal's and charismatics (note, charismatics also include charismatic renewal Catholics) claim to have personally experienced or witnessed divine healing. While not all of these claims would be legitimate, it would be foolish to think that all of them are not.
What do Catholics think of miracles occurring in Christian contexts different from their own? One verse that could come to mind is Matt 7:22 which suggests that even those not in a good relationship with God have the capability of casting out demons and doing mighty works in Jesus name. Conversely, Mark 9:38-41 suggests that all those who do such things in Jesus name are not "against us" and "will by no means lose his reward".
What do Protestants think of the undoubtedly miraculous events surrounding the lives of the saints and also the Marian apparitions at Guadalupe and Fatima?
Any book suggestions exploring the theology of this topic would also be appreciated.
