O abyss! 0 eternal Godhead! 0 deep sea! What more could you have given me than the gift of your very self?
You are a fire always burning but never consuming; you are a fire consuming in your heat all the soul's selfish love; you are a fire lifting all chill and giving light. In your
light you have made me know your truth: You are that light beyond all light who gives the mind's eye supernatural light in such fullness and perfection that you bring clarity even to the light of faith. In that faith I see that my soul has life, and in that light receives you who are Light…
Truly this light is a sea, for it nourishes the soul in you, peaceful sea, eternal Trinity. Its water is not sluggish; so the soul is not afraid because she knows the truth. It distills, revealing hidden things, so that here, where the most abundant light of your faith abounds, the soul has, as it were, a guarantee of what she believes. This water is a mirror in which you, eternal Trinity, grant me knowledge; for when I look into this mirror, holding it in the hand of love, it shows me myself, as your creation, in you, and you in me through the union you have brought about of the Godhead with our humanity.
(Saint Catherine of Siena)
