The Collect Prayer for the Daily Mass for the Feast of St. Catherine of Siena.

O God, who set Saint Catherine of Siena on fire with divine love in her contemplation of the Lord’s Passion and her service or your Church, grant, through her intercession, that your people, participating in the mystery of Christ, may ever exult in the revelation of his glory. Who lives and reigns with you in the unity of the Holy Spirit, on God, for ever and ever.
