 Richard Swinburne has long developed and defended a type of three-self Trinity theory which in the eyes of most critics seems to be “a fairly straightforward form of tritheism” (Alston 1997, 55. See also Clark 1996; Davidson 2016; Feser 1997; Howard-Snyder 2015a; Moreland and Craig 2017; Rea 2006; van Inwagen and Howard-Snyder 1998; van Inwagen 2003, 88; Vohánka 2014, 56). In a series of articles and books Swinburne’s views have changed in significant ways (Swinburne 1988, 1994, 2008, 2018), but this entry focuses on his latest work on the Trinity.
