Recently I was party to a conversation between pastors regarding the ceremonies of Passiontide and Holy Week. One fellow said that he couldn't see the point in leaving out the Gloria Patri during Passiontide. That brought to mind this famous quotation from Chesterton's essay, "The Drift from Domesticity."
One of the first principles of liturgical, churchly thinking is that our fathers in the faith deserve our honor and respect. The liturgy is, first and foremost, a gift, an inheritance, something handed down from our fathers. Let us not be ungrateful, snide, or know-it-all children.
