Calvary Ladies Bible Class: This is a small group experience examining the Scriptures using the International Bible Study and learning how to apply the words to our daily living. The Ladies Class meets in the parlor.

Calvary Men's Bible Class: The Men's Bible Class has been in existence since the beginning of the Church. The purpose of the class is to discuss the International Bible Study lessons and exchange ideas and views on the material presented. We emphasize open discussion and those who serve as teachers avoid lectures! We are composed of men who are married and single, interested in promoting the word of Christ. We meet in the Church Library located back of the Apostle's Room Hall.

Wesley Fellowship Class: This class gathers in the Apostles Room in a circle near the stage following the 15 minute Sunday School opening which is held in the Apostles Room. Members are made up of long and short term members, couples and singles. Most are retirement age or above, however persons of any age are welcome to join. Our lessons are from the "Adult bible Studies" or whatever the person that is teaching wishes to use. Numerous members of the class take turns teaching.

Generations Class: This class got it's name from the fact that the class has members from several generations (parents and their adult children). Anyone is welcome. We have recent post High School graduates through those that are retired. It is truly a span of generations. The study material is selected by a class officer and approved by the class. In 2008, the first study was  on the Book of Proverbs. Members take turns teaching or finding a teacher. Most lessons are in discussion format. The class also holds socials and service projects. Come and join us. We meet in the Basement Social Hall.

Good News Class: This class is made up of both singles and couples with most members being in their 30's and 40's. We do not do
traditional Bible Studies but instead select study books that we feel help us in our daily lives to become better Christians. A favorite author is James Moore. Whose life application books combine humor and reference. As a class, we host the Pentecost Breakfast and support
charities such as the Children's home in Mechanicsburg. The class meets in the Overflow Room beside the Sanctuary.

The Possibilities Class: This class, welcome to all ages, is an intergenerational class that meets in the room beside the Church Library. This study group is a discussion based class that focuses on growing in our Christian faith. The experiences shared by the class members are prompted by questions from the thematic study guides chosen by the class. All are welcome to share either in listening or participating in a discussion.
