You read the title correctly.
Written in 1969, Helping The Retarded To Know God: A Guide for Christian Teachers of the Mentally Handicapped provides readers with tips and tricks to indoctrinate even the simplest of minds into Christianity.
I don’t know if the 112 pages or the cover is more offensive…
Not sure if you want to buy it? Maybe this review will help.
