This is only half the original book. I'm unsure why this isn't made very clear in the description. Instead of telling us the contents, it should have a note saying this is missing the sections on soteriology, ecclesiology, and eschatology.

This needs to be at a much, much lower price if I can buy all the items individually for 33% less, and it is even advertised here as so!

Why is this not the 2015 edition?
