Catherine de Hueck is a person in every way big. And the bigness is not merely physical: it comes from the Holy Ghost dwelling constantly within her, and moving her in all that she does. I never saw anyone so calm, so certain, so peaceful in her absolute confidence in God.

She was full of the love of God; and prayer and sacrifice and total, uncompromising poverty filled her soul. She had tremendous spiritual vitality of grace, a vitality which brought with it a genuine and lasting inspiration, because it put souls in contact with God as a living reality. And that reality, that contact, is something which we all need.

―Thomas Merton, writing as a new Catholic, in The Seven-Storey Mountain
