Other resources of note, is a helpful bibliography here, a great post by Daniel Wallace about his friendship and letter writing correspondence with Moule, here, and a sermon written by former student, Dr. Rowan Williams, and also former Archbishop of Cantebury, here.
A man's legacy is often defined by those for whom he mentored. With former students such as James D.G. Dunn, Graham Stanton, and Andrew Lincoln, Moule's legacy is a great one indeed, and continues to shape the contours of serious NT scholarship today.
At the risk of getting the details wrong, I was fortunate to have lunch with the aforementioned Lincoln at the SBL annual meeting in Baltimore. I asked him about Charlie and one of the stories he told me was that Charlie could be routinely found reading his well worn Greek New Testament in a park behind Cambridge University at about 6:00 in the morning. Lincoln told me that was Charlie doing his devotions.
Charlie was known as a man of profound faith and genuine humility. It was friend and fellow NT giant, Joachim Jeremias, who said of Moule, "In him could be seen no trace of original sin."
Happy Belated Birthday, Charlie!
