Sabbath School Lesson Study Impact on Biblical Literacy and Retention

Sabbath School is the Adventist Church's longest-running and most widespread discipleship programme, operating in virtually every congregation worldwide. Using the quarterly *Adult Bible Study Guide*, it provides structured, systematic Bible study through 13-week cycles covering biblical books and themes. The Adventist Encyclopedia identifies four historic purposes: Bible study, fellowship, community outreach, and world mission support. Qualitative evidence strongly suggests that regular Sabbath School attendance builds biblical literacy through cumulative exposure to Scripture and facilitates retention through small-group relationships and church integration. However, no rigorous quantitative study has measured the biblical literacy levels of regular Sabbath School attendees vs non-attendees, nor has any longitudinal study correlated Sabbath School participation with member retention rates. Anecdotal and institutional evidence suggests declining Sabbath School attendance across Western divisions, with members increasingly arriving only for the worship service. If Sabbath School attendance correlates with retention — as theory and limited evidence suggest — then declining participation may be both a symptom and a cause of the broader membership retention crisis. The denomination urgently needs empirical research quantifying these relationships.
