This article first discusses the relation of popular piety to the liturgy, stressing the differences between them and the fact that there is no competition between them, but rather there is desirable complementarity: popular piety services on one side prepare for the liturgy, and on the other they help to deepen the experience of the latter one. The specifics of the preaching the word of God in the context of popular piety determines the distinction, at least in the Polish language and practice, between “the sermon” and “the homily”. The first one describes preaching in the context of popular piety, whereas the second term “the homily” is reserved for the preaching during the liturgy. The specifics of the sermon is influenced by the non-liturgical context of preaching, as well as the extended group of people that might preach, as well as the language that can be less restricted than the language of the homily.
