Among the multitude of expositions on the Apostle's Creed, written throughout church history, one in particular has not received the attention it deserves. Herman Witsius, best known for his  The Economy of the Covenants (part 1) and (Part 2), published an exposition of the Apostle's Creed under the title Sacred Dissertations on the Apostle's Creed (Part 1) and (Part 2). If you are interested in doing further study of Witsius' work  you will find an Analysis of the Economy of the Covenants and On the Character of a True Theologian to be helpful.
