Dallas Theological Seminary, which was founded by Chafer, is so embarrassed by his "masterpiece" that they let it go out of print!
Most outstanding institutions founded through faith in Christ, seem to have been later targeted by worldly systems to control the previous righteous work of their founders.
Just look at how many universities in the US founded upon faith in God through Christ, today espouse agnosticism and atheism, and even promote any New Age belief over faith in God through Christ.
I tend to believe its a 'worldly' thing.
Regardless, I've found his Systematic Theology well studied and versed.
