People cannot receive information about philosophy while being themselves dispensed from philosophising, thinking. This requirement is reasonable, since “all men desire to know”. A dualist approach to philosophy and theology obscures that they are the same. Revelation is immanent within the thinking person and grace, pace Thomas, is not extrinsic. Ecumenism, the principle, underpins this. So the philosophy of theology transcends external confessionalism, as does Christian faith itself.
