Socializing is way down on the list of priorities. Without it they are dead. Take a peek around the edge of the paper and discover a world of grand and glorious teaching tools. Some, naturally, are age oriented. Others, are financially restrictive.
Geographical location affects availability, and education level influences usability.
But give consideration for something different anyway. Even if your class does prefer a quarterly, consider using a theme-based undated quarterly. If some in your class wish to investigate contemporary topics but others don't, work with your Pastor and Sunday School Superintendent and possibly start another class, and after a pre-determined amount of time to study the topic, recombine the two classes for the next topic. This will keep unity yet meet needs. If these ideas are inappropriate, maybe this is the perfect time to start a Bible study during the week, either at the church or in someone's home.
