📝 About this app
Sabbath School Quarterly app allows you to take your Seventh-Day Adventist Biblical studies wherever you bring your phone. Most Seventh-Day Adventist churches teach on the same topic or reading in a given week, as each quarter of the year has a different theme that reflects Bible, doctrinal, or church lifestyle teachings. Thus the lesson booklet is called quarterly.
This app provides you with all of the Sabbath School quarterlies for the current and previous three quarters.… View full description on the official store →
