I have sympathy with Hart’s reservations vis a vis the antithesis, in this case, concerning Greek thought, mentioned early in this discussion. Indeed speaking covenantally, wisdom is ‘stolen’ because the true ownership/authorship/provenance is not only ignored but boldly denied. But at the same time, it borders on ad hominem when Christians treat secular thought like its cryptonite simply because its authored by unbelievers. So a simple error occurs, and as a result, we lose out on some fascinating stuff, and potentially some real wisdom. So we have to, its crucial to, keep the covenantal categories clear; and the same time we can’t fear the contributions of the history of philosophy or whatever it might be, presuming that God can’t work through unbelievers, or that there is really ever any possibility of handling anything in this world which is not, despite our best efforts, crying out the praises of the one true God.
