The use of alternative models in theology is a comparatively recent development. The tradition had been that a theologian should know the truth and demonstrate the falsity of all other pretentions. In the post-modern world all theological models compete on an even playing field with all others. He should have known from Kuhn's work that there is no final or correct paradigm in science or in theology. It seems simpler to avolid Kuhn's used of the term paradigm in favour of the simpler word model.
Nothing hangs on the dividing line between models and paradigms.
It is also important to note how Margaret Masterman showed that Kuhn was working with at least three quite different kinds of paradigm. Masterman's metaphysical paradigms are large scale world views. Masterman's sociological paradigms picture the stated and unstated rules for a community, or a group of scientists, or a church denomination. Construct paradigms in Margaret Masterman's terminology picture one component of a bigger paradigm. For example the double helix pictures the structure of the DNA molecule as a key component in the bigger paradigm of biochemistry.
