The word 'homiletical' is often used to describe a style or approach related to religious or moral exhortation. Synonyms for 'most homiletical' could include 'most sermonizing', 'most didactic', 'most preachy', 'most moralistic', or 'most instructive'. These words all convey the idea of teaching or preaching with a focus on moral or ethical instruction. While some might find a homiletical style of speaking or writing to be helpful or inspiring, others may find it off-putting or overly moralizing. As with any style or approach, finding the right balance between instruction and inspiration can be key to reaching a diverse audience.
