Fr. Scalia is a very exact person when it comes to the Church’s rules and doctrines. You’re not supposed to have a eulogy at the funeral Mass, so he wouldn’t and didn’t. Every point was tied into the doctrines which Justice Scalia (and hopefully all of us Catholics) believe. Fr. Scalia was very careful not to assume that his father was in Heaven already, and asked for prayers from us, which I’m sure his father would have wanted (and indeed, so would I, but my funeral is unlikely to be broadcast on TV.

)
I thought the homily was a masterpiece, although in places perhaps a bit provocative considering who-all was in the congregation (e.g. vice president, some of the other Justices). The “memento mori” aspect was not omitted, and Jesus was central.
Also, Justice Scalia did sometimes attend English-Language Mass. (Granted, not all that often, but sometimes.)
