A conventicle originally signified no more than an assembly and was frequently used by ancient writers for a church. At a semantic level conventicle is a Latinized synonym of the Greek word for church, and points to Jesus' promise in Matthew 18:20, "Where two or three are met together in my name."

Anabaptism is a Christian movement which traces its origins to the Radical Reformation in the 16th century. Anabaptists believe that baptism is valid only when candidates freely confess their faith in Christ and request to be baptized. Commonly referred to as believer's baptism, it is opposed to baptism of infants, who are not able to make a conscious decision to be baptized.
