 There are many kinds of hybridists: while they all think a turn to faith is necessary at some point, some seek to establish little more than the bare existence of God before turning to faith for greater details. Others think it is possible to develop a more robust understanding of God from within the bounds of reason and sense-perception. Indeed, in recent years the so-called “ramified natural theology” movement has sought to use our natural faculties to demonstrate (or show to be highly probable) robust doctrines that go well beyond bare theism—for example, specifically Christian doctrines such as that of the Trinity, the resurrection, or the historical authenticity of certain miracles or biblical prophecies (Swinburne 2003; Newman et al. 2003; Gauch Jr. 2011; see  section 4 below).
