Thoughts on the Eucharist (from the Dialogue of St Catherine of Siena, No. 112; the Father speaking)
Dearest daughter, contemplate the marvelous state of the soul who receives this bread of life, this food of angels, as she ought. When she receives this sacrament she lives in me and I in her. Just as the fish is in the sea and the sea in the fish, so am I in the soul and the soul in me, the sea of peace. Grace lives in such a soul because, having received this bread of life in grace, she lives in grace. When this appearance of bread has been consumed, I leave behind the imprint of my grace, just as a seal that is pressed into warm wax leaves its imprint when it is lifted off. Thus does the power of this sacrament remain there in the soul; that is, the warmth of my divine charity, the mercy of the Holy Spirit, remains there. The light of my only-begotten Son's wisdom remains there, enlightening the mind's eye. [The soul] is left strong, sharing in my strength and power, which make her strong and powerful against her selfish sensuality and against the devil and the world.
