The Red Mass tradition dates from the 13th century. It is named for the red vestments worn by the priests and the scarlet robes worn by the Lord High Justices. Liturgical red is proper for a votive Mass of the Holy Spirit and symbolizes a willingness to defend the truth. In the United States today, a Red Mass is celebrated in most major metropolitan areas and is attended by judges, lawyers, public officials, law faculty, and law students.
