In my opinion, this is one of the best $250 investments you could possibly make. For $250 you can have the complete works of Martin Chemnitz available in English, published by Concordia Publishing House.
Martin Chemnitz's major theological works translated into English are now available in beautifully bound matching hardback volumes to endure years of study and use.
These eight books purchased individually would retail for $419.92, but when you buy the complete collection save 34% and get them for only $249.99, with free shipping!
The series includes:
Examination of the Council of Trent, Volumes I-IV
The Lord's Supper
The Lord's Prayer
The Two Natures in Christ
Loci Theologici, Volumes I&II
