Those of us who have lived in the Diocese of Arlington are familiar with the eloquence of Paul Scalia's homilies. What a difficult task it must have been to give the homily for his own father and before such audiences.
This homily is not sentimental, but it is moving and full of power. It is worth the sixteen minutes. Rhetoric is a dying art and the word "rhetoric" has become a synonym for sophistry, but this is worthy of a Demosthenes or a Cicero.
I will not analyze the homily in detail. Michael Pakaluk provides an excellent analysis in Crisis.
Justice Clarence Thomas, whom Paul Scalia reconciled back into the church, was a lector doing a reading from Romans. Senator Cruz, a Southern Baptist, interrupted his campaign to attend the funeral. You can read an account of the funeral in the New York Times.
