Who wrote these lines? It may surprise you!

"A free theologian does not deny, nor is he ashamed of, his indebtedness to a particular philosophy or ontology, to ways of thought and speech. These may be traditional or a bit original, old or new, coherent or incoherent. No one speaks exclusively in Biblical terms”

Yes, these words come from the pen of Karl Barth, and his essay "The Gift of Freedom". Barth was not opposed to indebtedness to philosophy! But, he goes on to add, their philosophy etc. "will be subject to criticism and controlled by his theology, and not conversely". This latter claim is not entirely unproblematic, but that is an issue for another day.
