MEDITATION
ACCORDING to the definition of Pope Pius IX, the immaculate conception of the Blessed Virgin Mary is that privilege by which she was preserved, in view of the merits of our Saviour Jesus Christ, from original sin in the first moment of her conception.
By solemnly proclaiming the dogma of Mary's immaculate conception, the Church confirmed anew the fundamental principles of Christianity which in our times are so frequently attacked, derided, or forgotten. God reserved the solemn proclamation of this dogma, which seemingly has no practical bearing on the Christian life, for our age, to recall to our mind the doctrines resulting from it.
PRACTICE
THE most important of these doctrines is that of original sin, which to-day is rejected by many as a debasement of human nature, and is forgotten by others as having no practical influence on our moral state. By the promulgation of the doctrine of the immaculate conception of the Blessed Virgin Mary, the Church solemnly declares and defines as an article of faith, that the Blessed Virgin Mary is conceived without the stain of original sin by a special privilege and grace of God. If, then, Mary's sinlessness is an exception, the general rule remains in force, and all other human beings enter this world in the state of original sin.
Thus, by the proclamation of the dogma of the immaculate conception, the Church combats human pride and sensuality, the foremost vices of the age.

Prayer
MARY, unsullied lily of heavenly purity, I rejoice with thee, because at thy conception's earliest dawn thou wast full of grace and endowed with the perfect use of reason. I thank and adore the ever-blessed Trinity, who gave thee such high gifts. I am overwhelmed with shame in thy presence, to see myself so poor in grace. O thou who wast filled with heavenly grace, impart some portion of it to my soul, and make me share the treasures of thy immaculate conception.
