This colorful book explains, in simple language, the sometimes confusing matter of Holy Days of Obligation. It discusses each of the holy days and gives the scriptural basis for each. Children will gain a better understanding of why and how the Catholic Church celebrates these days, as they become involved in the actual stories of how these days evolved. Holy days include: the Immaculate Conception, Christmas, Mary, Mother of God, the Ascension of the Lord, the Assumption, and All Saints' Day. The book also touches on the meaning of an obligation, the varieties that might appear from diocese to diocese, as well as Sunday being a Holy Day of Obligation. This charming addition to the "Child's Guide" series, the first to treat this topic, can be used as a resource by: Catholic elementary schools and pre-schools; parish religious education programs; home schoolers; and, Catholic parents and grandparents, who read religious books to their children, or buy these books for them.
