...the meagerness of our [evangelical] ritual language and our purgation of sacrificial imagery from the central sacrificial context of the Eucharist, instituted by our Lord himself, has led on the one hand to a sort of semi-Gnostic pilgrimage to the latest Christian fad, but also, because the ritual sacrifice is in our very marrow, to the invention of our own ritual—the altar call. So it is that in churches which have no altars and do not call the Eucharist a sacrifice of any kind that people walk up to the altar (aka, stage) and offer themselves up to God, or ask for his grace to overcome some temptation or sickness of struggle, or ask for the grace of salvation, or what have you.
