The Crux Fidelis and the Vexilla Regis can be found in the Graduale and are used Liturgically on this day. Both these Hymns have been revised, but the older versions below can also be used. The scan of the Crux… is from the 1961 G.R. the scan of the Vexilla is from the 1910 L.U.
Below is the ‘original’ version of the Vexilla Regis not the modern version used for Vespers during Passiontide, for feasts of the Holy Cross, and as a processional Hymn on Good Friday.
