Quick question. I know that the liturgy up until Vatican II was all in Latin, but the sermons were in the vernacular. Was this the case throughout late antiquity, middle ages, and renaissance or were homilies given in Latin as well? If homilies were given in Latin, how were the lay people suppose to understand the message, given that the vast majority were illiterate and spoke a native tongue?
I am asking, because I was thinking about the beautiful cathedrals/churches, and how the structures exterior and interior told the story of the gospel through art work. This lead me to wonder about the homilies, and whether the people were able to understand them during the time. Bit erratic, but whatever.
