“The creature most filled with the love of God Himself was the Immaculata. We know she never contracted the slightest stain of sin; she never departed in the least from God's will. United to the Holy Spirit as his spouse, she is one with God in an incomparably more perfect way than any other creature. In fact, we can say that the Holy Spirit does not act except through the Immaculata, his spouse. That is why she is the Mediatrix of all graces of the Holy Spirit. And why we can be holy by staying close to her throughout our life."
- St. Maximilian Kolbe (on the Feast of the Immaculate Conception)
