On Marian Devotion
“According to Matthew 5:8, the ‘immaculate heart’ is a heart which, with God’s grace, has come to perfect interior unity and therefore ‘sees God.’ To be devoted to the Immaculate Heart of Mary means therefore to embrace this attitude of heart, which makes the fiat — ‘your will be done’ — the defining center of one’s whole life.”
— Pope Benedict XVI as then Cardinal Ratzinger
