Worth knowing

The Church has honored 36 men and women with the tile of “Doctor of the Church” in recognition for their important contributions to theology and spirituality. Of those, only four are women: Saint Teresa of Avila, Saint Thérèse of Lisieux, Saint Hildegard of Bingen, and, of course, Saint Catherine of Siena. Saint Catherine is the only lay person to be honored as a Doctor of the Church.

For prayer and reflection

Eternal Trinity, Godhead, mystery deep as the sea, you could give me no greater gift than the gift of yourself. For you are a fire ever burning and never consumed, which itself consumes all the selfish love that fills my being. Yes, you are a fire that takes away the coldness, illuminates the mind with its light and causes me to know your truth.”—Saint 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 of 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,
one God, for ever and ever.

(from The Roman Missal)
