rom Keller's published works and what I know about him during my days at Redeemer, I think it is safe to at least conclude the following: 1) He believes in the framework hypothesis for explaining creation, which the PCA considers within the bounds of the Westminster Standards and do not require an exception. 2) It is not clear that Keller himself personally believes in Theistic Evolution, but he considers it a viable option for those who hold to Reformed convictions. Whatever his own personal convictions, he has never taught either Creationism or Theistic Evolution as THE correct view. He has, however, clearly spoken out against Evolution as a theory of live. 3) Whatever his views on evolution, Keller has clearly stated that he believes the historicity of Adam to be the only viable option for Reformed Christians. However, he is not willing to say it is salvific issue. He also believes that there is room for believing that Adam may have evolved from hominids, although he has not stated that this is his personal view and has not taught it at his church. Most of this can be gleaned form his Biologos essay at http://biologos.org/uploads/projects/Keller_white_paper.pdf; I've filled in the gaps based on my own experience.
