When I was writing a response to an email query, I looked up a link for Pope Benedict XVI’s book Jesus of Nazareth (Vol. 1).
I found that – at the time of this writing – it is on sale (at least for US buyers) through Amazon. Hardcover – $9.98.
If you don’t have the book, I suggest thinking about getting it at this price. A good gift, perhaps. Have an extra copy to mark up as you read.
His Holiness’ book has one of the best explanations of the uses of and limitations of the so-called historical-critical approach to Scripture, how divine inspiration worked, and very useful material for reflection on, for example, the Lord’s temptations in the desert.
FYI & FWIW
And don’t forget to refer to Benedict XVI as the "Pope of Christian Unity".
