It is an exceptional homily, and every Christian should hear it. Note in particular the section around 12 minutes into the homily, where Fr Scalia quotes his father writing about funerals and eulogies. Justice Scalia had written about "God's inexplicable mercy to a sinner." This is a key phrase, as is Fr Scalia's point that Christ died and rose for all of us, and for each of us.
The Mass occurred in the Basilica of the National Shrine of the Immaculate Conception in Washington DC. The archbishop of Washington, and the bishop of Arlington Virginia were also at the Mass praying for Justice Scalia.
