Timothy George on  Benedict XVI, the great Augustinian :

Not long ago, Pope Benedict XVI made a personal donation to the restoration of the Basilica of St. Augustine in Annaba, Algeria, the site of the ancient town of Hippo Regius, where the greatest theologian of the ancient church served as bishop from 395 to 430. It was here on September 26, 426, that Augustine met with his flock to name his successor as the bishop of Hippo, the presbyter Heraclitus.

Also today, Thomas G. Guarino has a theological appreciation of Benedict XVI :
Although we are formally speaking of Benedict’s initiatives as pope, it is probably best to discuss the theological body of work he produced from 1981 to 2013, rather than simply his last eight years as bishop of Rome. For if one conjoins his papacy with his long service as Prefect of the Congregation for the Doctrine of the Faith, then his lasting theological legacy comes into sharper focus: For over thirty years, Benedict has effectively served as the chief interpreter of the Second Vatican Council.
