I was quick to dismiss this as coincidence, until discovering that Father Milward is a renowned Shakespeare scholar. From "Fifty Years of Milward," in the Spring, 2002 Shakespeare Newsletter:
Milward, originally from England, has spent a half century teaching at Sophia University in Tokyo, Japan. He is the founder or co-founder of numerous societies and organizations in Japan, most notably the Renaissance Institute, founded in 1971 to promote the scholarly vision of continuity between the Middle Ages and the Renaissance, in the spirit of C. S. Lewis. He is the author of over 300 books, which range from scholarship to poetry to educational guides for Japanese students.
Milward's ["Fifty Years of Shakespeare, 1952-2002"] lecture at Boston College marked the establishment of the Peter Milward Special Collection (links mine) at Burns Library, which now has a more or less complete collection of Milward's Shakespeareana, and a generous selection of his other works. Boston College's scholarly journal, Religion and the Arts, is planning a sizable volume of essays on Shakespeare and the Reformation. Milward was therefore invited as a major figure in establishing Shakespeare's Reformation contexts, especially through his landmark book, Shakespeare's Religious Background, which argued for both Catholic and Anglican contexts.

Milward, it turns out, was one of the first to argue that Shakespeare was a practicing Catholic. He has also written extensively on Gerard Manly Hopkins (he is the honorary president of the Tokyo branch of the Hopkins Society of Japan), and T.S. Eliot.
While still unlikely, it seems entirely plausible that Reed may have written Father Milward to congratulate him on some publication on Shakespeare, or to argue some minuscule point of Eliot scholarship.
