But 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 and so forth) on the grounds that such things CAN be superstitious or idolatrous or that some people might suppose 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.
