'...to reject, marginalize, trivialize or be suspicious of the sacraments (and quasi-sacramental acts such as lighting a candle, bowing, washing feet, raising hands in the air, crossing oneself etc.) on the grounds that such things can be superstitious or idolatrous, or that some people might suppose that by doing them they are putting God in their debt, is like rejecting sexual relations in marriage on the grounds that it's the same act that, in other circumstances, constitutes immorality.'
Tom Wright, Surprised by Hope, p.275.
