You are probably familiar with the polemical rhetoric of church father Tertullian, “What has Athens to do with Jerusalem?” It set the tone in the early Christian centuries for the rejection of philosophy (his target then being neoplatonism). His reason for doing so was a laudable desire to affirm the simplicity and availability of knowledge of God through faith, in contrast to pagan metaphysics and dialectics in the style of Athens’ Plato, and his successors. Tertullian’s key text in doing so was Paul in Colossians 2:8 saying, “see to it that noone takes you captive through hollow and deceptive philosophy which depends on human tradition and the basic principles of this world rather than on Christ”.
He was not however the only voice in the church of the first three centuries, because other Christian theologians like Clement of Alexandria and Origen, schooled in the philosophical air of Alexandria, were much more aware of the vital need to connect faith and reason, Bible and philosophy, in order to convince educated pagans to become Christians. They recognised (as did Calvin later) that Paul’s target in Colossians quoted above was not philosophy per se but only philosophy that is incompatible with Christ as sufficient Saviour and sovereign Lord. Origen for instance quotes Plato and has been accused of adopting the “middle Platonism” of his day; yet he was first of all a Bible commentator, and always saw the Bible’s account of creation and the Fall as deeper and more accurate than that of Plato. There is bad philosophy, but there is also good philosophy.
The debate continued through the later church fathers. Athanasius and Augustine welcomed ideas drawn from prechristian philosophy, whilst recognising how Christ transforms its ideas about God, the soul and immortality. In the middle ages great thinkers like Anselm, and particularly Aquinas, recognised the validity of drawing upon reason, whilst relying upon faith, in the pursuit of knowledge of God and in finding ‘analagous’ language, however imperfect, to describe Him.
The Reformation and subsequent enlightenment periods saw an increasing separation of faith and reason, perhaps not helped by the failure of the Protestant theologians to engage in serious metaphysical analysis, and Luther’s description of the philosophy of men like Aristotle as “the devil’s whore”! The Church became (not entirely justifiably) suspicious of the influence of Aristotle, with his emphasis upon this-worldly knowledge. Then following Descartes, rationalist philosophy through David Hume and others appeared at least to disconnect what can be known by reason from the experience of faith.
The consequence was the separation of science as a discipline of objective “knowledge” from religion as an exercise of subjective “faith”. This has proven inaccurate as an understanding both of science and of religion, but it remains influential in public perception and policy.
This long painful divorce will be destructive for religion and for society. Faith is and needs to be reasonable, and seen as such. In a secular culture which is growing more and more hostile to faith, it is my guess that the separation will be held up as evidence that faith is “unreasonable” and worthy only of marginalisation and muting. A brave new world of human reason and devoid of faith is the future some wish for already, but cries of “freedom and equality” fail to recognise that enforcing one inevitably requires crushing the other.
Faithful Christian philosophers and thoughtful apologists are going to be needed.
