O God, by your grace your servant Catherine of Siena, kindled by the flame of your love, became a burning and shining light in your Church, turning pride into humility and error into truth: Grant that we may be set aflame with the same spirit of love and discipline, and walk before you as children of light; through Jesus Christ our Lord, who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.
