Pohle-Pruess

The use of sacramentals remains optional, while to receive certain sacraments is of strict obligation....Educated Catholics may not relish all the sacramentals, but they know that the Church, as a kindly mother, supplies all reasonable needs and demands of her children, even those of the weak and the simple.

This is interesting because it comes after a comment about forbidding superstitious or contempt for the sacramentals. Reading between the lines here, there's a sense that use of sacramentals strictly speaking, is limited to those who are uneducated, and simple. Even in this, a defense of their operation. Never the less, the mother image is a nice one. And I think the fittingness of the use of sacramentals is notable.
