Thought that teaching is from nation of gods & earths, but I don’t know which one came first
The NOI was founded in 1930. The NGE was founded in 1964. The NGE gets their teachings from the NOI. The main difference is that the NOI has Restrictive Laws. In the NOI you can't drink or smoke and you have to go to the meetings. The NGE is more lax, we drink and smoke and have gatherings outdoors in parks and street corners. But their core teachings are the same.
The teachings are as follows;

*NGE teachings
**NOI teachings
Basically The NOI had lessons that their followers were supposed to memorize and recite by heart. In 1964/65 one of the ministers, Clarence 13X took the lessons out of the temple and began teaching them on the street. He drank and smoke while teaching the lessons, which is a no-no. He was murdered in 1969 and his followers continued his legacy. There is an Allah School in Mecca (Harlem) and they have parliaments every month and a Show and Prove every year on Clarence 13X's birthday, whom we call The Father.
If you work the internet you can find the lessons pretty easily.
