... I seem to remember that after the founders death, the church became trinitarian.

Yes, one portion did:

That group was led by Joseph Tkach.

He enlisted CRI to try to get their orthodoxy re-focused.

The rest fractured into 300+ groups (as this thread article mentions) in less than a decade. Most of the fracture was over "governance" issues; some of it was still highly doctrinal.

Armstrong's illustrator for that booklet was Basil Wolverton of MAD magazine...how appropriate.
