Calpurnia's church congregation sang hymns from memory, relying on oral tradition rather than written texts. They did not have hymn books due to economic hardships and a lack of resources, which prevented the purchase or printing of such materials. This practice fostered a deep communal experience as everyone participated collectively in the singing from recollection. The absence of hymn books also highlighted the resilience and adaptability of the congregation in expressing their faith.
