Is there a difference?
Theistic evolution implies more of a deistic approach while Evolutionary Creation implies more of an active role for God in the world. Proponents of these points of view often wrestle with terminology.
E.G.: Howard Van Till refers to his position as the fully gifted creation perspective.
a vision that recognizes the entire universe as a creation that has, by God’s unbounded generosity and unfathomable creativity, been given all of the capabilities for self-organization and transformation necessary to make possible something as humanly incomprehensible as unbroken evolutionary development.
