Christus factus est (Christ became obedient) is taken from Saint Paul's Epistle to the Philippians. It is a gradual in the Catholic liturgy of the mass on Palm Sunday, Maundy Thursday and Good Friday.
Text
The text is derived from Philippians 2:8–9.
In the Catholic liturgy it used as Gregorian gradual on Palm Sunday, Maundy Thursday and Good Friday. The melody is found in the Graduale Romanum, 1974, p. 148. Over the centuries the text has been set in music by several composers.
Anton Bruckner has set the text three times in music. He set it first in 1844 as gradual of the Messe für den Gründonnerstag (WAB 9). The second setting Christus factus est, WAB 10 of 1873 is a motet in D minor for eight-voice mixed choir, 3 trombones, and double bass quintet ad libitum. The third setting Christus factus est, WAB 11 of 1884 is a motet for SATB choir a cappella in D minor. This third setting is with Locus iste and Ave Maria among Bruckner's most popular motets.
