I really like Alister McGrath. A formidable intellect, Evangelical in stripe but/and nuanced, honest and open. One of the few apologists (the only, probably) I've come across who will admit the weaknesses he sees in his own arguments.
I'm not a big fan of apologetics in general - especially in the sense that it often seems to be based on the premise that it's possible to present an objective intellectual argument or 'proof' so watertight that a person will be compelled to faith. Personally I don't think such an argument exists (and I think McGrath agrees, which is one of the reasons I like him so much - see above).
But also I don't think that it's the intellect that is the decisive factor in coming to faith. It is much more likely to be an emotion or subjective experience, an answer to a felt need - something personal, existential - that is the catalyst for that shift. Not to mention the necessity of some kind of leap of faith - even if, in the moment, that leap is propelled by the strength of the felt 'rightness' of the experience.
One instance that is often held up as an example of an intellectual conversion is C.S. Lewis (by the by, McGrath is a big fan of Lewis). In that mythos, Lewis thinks his way into Christianity. That's all very well. But it's no coincidence that his autobiography is called Surprised by Joy. Further, I would argue that in an intellectual pathway to conversion it is the feeling of intellectual satisfaction, a sort of homecoming, a realisation, a feeling of coherence and discovery, that is the decisive thing. I also think it is no coincidence that Lewis persists in the popular memory as a whimsical storyteller more than as an intellectual (though he certainly was impressive in that latter regard).
Intellectual apologetics, or pathways to faith, are only 'effective' in as much as a person arrives at a subjective personal experience.
Though, that said, I loath apologetic approaches that seek to manipulate people into that space. I'll never forget how sick I felt when I read in The God Who is There that, by his own admission, Francis Schaeffer was prepared to risk the possibility someone might commit suicide due to the way his apologetic approach sought to deliberately bring people into a state of despair, as a precursor to offering them an 'antidote'. Repulsive.
I digress! But all that to say, as far as apologetics go, McGrath is pretty well as sound as they come, I reckon.
His scope is incredible. I suppose the book of his that I was most impacted by was his introduction to Christian theology, which gives space to multiple streams of thought. I also have on my shelf (purchased in Cambridge, actually, over 20 years ago) his anthology of Christian literature. And his Bible commentary. For all that 'humanities' stuff, he began his career by gaining a doctorate in molecular biophysics at Oxford, while also gaining a theology degree.
In this book, those threads of his life thoroughly intertwine: theology and the natural sciences in dialogue. Accessible but with a wealth of footnotes to spark further investigation if the reader is so inspired. It's excellent.
When he gets on to possible conversations between science and theology, his chapter on Theories and Doctrines, and particularly his treatment of the role of the imagination, is absolutely storming.
Good stuff.
So many great quotes, like this one:
"The first great enemy of science is not religion but a dogmatic rationalism, which limits reality to what reason determines to be acceptable. This simply locks us into the very narrow world of what reason is able to prove. And the universe seems to have a rationality that we can investigate, describe and represent – even though it sometimes seems to bear little relation to what human common sense is inclined to believe."
Or this,
"Looking back on my own exploration of my faith, I can see a worrying trend towards an overintellectualization of faith in my own early thinking. Yet as I grew in faith I began to appreciate the imaginative and aesthetic dimensions of Christianity, without losing sight of the importance of its intellectual capaciousness."
Or this, with its salutary message for all 'sides',
"The epistemic dilemma of humanity is such that we cannot prove the things that matter most to us – at best, we can prove shallow truths. It’s not a comfortable situation but we have to get used to it, and not seek refuge in the illusory utopian world of the New Atheism [or Fundamentalism?], which holds that we can prove all our valid core beliefs."
That honesty:
"I don’t regard the beauty or order of the world as proving there is a God. Rather, I see my Christian belief as chiming in with the beauty and order of nature. The theory fits or accommodates our strange world – not perfectly but in an intellectually and aesthetically satisfying way."
