Azizi, no, that song was not sung in the church but in the church's rec. hall.
Those sessions were led by the Mormon Minister and at that time no offense or insult was meant. I did'nt even know what we were singing!

What I heard was ..chewing gum, erasers at the door! Didn't know until years later the real lyrics.
If you recall, in those days there were very few black folks in the Mormon Church.Also at that time, there wasn't a black person within 200 miles of us.
