St Barbara, Virgin and Martyr
I spoke of Thy testimonies before kings, and I was not ashamed: I meditated also on Thy commandments, which I loved. * Blessed are the undefiled in the way: who walk in the law of the Lord.
(Psalm 118:46-47,1 from the Introit of Mass)
Deus, qui inter cétera poténtiae tuae mirácula etiam in sexu frágili victóriam martýrii contulísti: concéde propítius; ut, qui beátae Barbarae Vírginis et Martyris tuae natalítia cólimus, per ejus ad te exémpla gradiámur.
O God, who among the wonders of Thy power hast granted even to the weaker sex the triumph of martyrdom: mercifully grant that we who celebrate the heavenly birthday of blessed Barbara Thy virgin and martyr, may, through her example, advance nearer to Thee.
