The communal nature of public worship is shaped and affirmed by liturgy, which is a script of a congregation’s unfolding thought processes, social interaction, and psychological movement. Liturgy proceeds in stages of collective activities that can be both physical (outward) and psychological (inward); it helps a worshiping community gradually move into the presence of God.
Progressive-emotive sermons are generally classified either by their relationship to the source material (topical, textual, expository) or by the method of their argument (inductive, deductive, dialogic). The progressive-emotive sermon, however, is defined by its intended impact on the listener.
Catechetical preaching, or preaching sermons based on the consecutive “Lord’s Days” of the Heidelberg Catechism, is a centuries-old tradition among Reformed churches and has historical roots in the Calvinistic reformation of sixteenth-century northern Europe.
