There are many different kinds of purity programs at local churches in which teenagers can enroll. These programs consist of several Bible study and relationship classes, followed by a purity ceremony (kind of like a graduation). At these purity ceremonies, students make their vows of purity and virginity publicly in front of a congregation (consisting mainly of family and friends). As they make this vow, they are presented with a purity item, most often a ring. This item is presented to them by their parents or an adult guardian. It represents and symbolizes their vow to stay pure and abstinent until marriage.
For more information about these formal purity ceremonies and classes, contact your local church organization.
