Heidelberg Catechism Commentary Manuscripts
The purpose of this paper is to present and to sum up the results of a historical and theological research into the use of the Heidelberg Catechism in Transylvania. It focuses on those commentaries on the Heidelberg Catechism which have never been printed because of various reasons, but are still in use for almost two centuries in the schools and pulpits of the Church. Most of the manuscripts mentioned in this study –mainly from 17th-18th century – have never been extensively researched.
