“The origin and traditional customs associated with Halloween require no other explanation than that they are examples of the kinds of festivity that served as a means of celebrating the various holy days of the Catholic Liturgical Year. This includes everything from masquerades, feasting, and the associations of a given day of the year with supernatural or spiritual truths.
I would draw a distinction between the violent, macabre imagery that characterizes the modern appropriation of Halloween as a kind of secular celebration and the more traditional customs that are characteristic of a Catholic cultural ethos. The descent of Halloween into the madness of an annual fright fest is a relatively recent development, but the true substance of Halloween belongs to the Church. Halloween (or “All Hallows Eve”) is the festive precursor to the celebration of the Church’s public commemoration of All Saints Day.”
