In the Catholic Church, Holy Days of Obligation or Holidays of Obligation, are also called Feasts of Precept, are the days on which, as canon 1247 of the Code of Canon Law states that on Sundays and other holy days of obligation, the Christians faithful are obligated to take part in the Mass. Furthermore in time of Catholic Holy days of obligation the faithful are to abstain from works and affairs which go against the worship to be given back to God. In the US, Feast of the Immaculate Conception and Christmas are parts of those obligations.
The Feast of the Immaculate Conception is celebrated on December 8 and was established as a universal feast in 1476 by Pope Sixtus IV Here the privileged feast of Mary, that she likes between all her dedicated feasts, the one that she wants to see us celebrate with the enthusiasm and with commitment to the Church, and to which the most invaluable favors are attached. Mary, having to carry in her womb the Author of Holiness, could be soiled with no stain; it was not appropriate that the demon had some right on that which only came in the world to crush his head. Not, never this impure spirit did not have any power on this great Virgin predestined to be the Mother of God. It was not given to him to sit, even a moment, on this throne raised for the great Trinity; never it entered this sanctuary prepared for the Verb makes flesh, for the Redeemer of mankind. Satan was defeated again, as at the day of its revolt against the Almighty God, the day when Mary was conceived without sin.
