There were lots of black females in the congregations. And a lot of cong were mostly black bros and sis and I felt they were the best congregations because they were generous and took care of the Bethelites with food with clothes with rides with money. But there were no interracial marriages at bethel. First marriage I remember in bb was mid 70s , white bro from bindery maintenance married a black sis.
Some of these young bros left bb to marry local females, some with 4 or 5 kids. One bro I knew was very involved with a sis with many kids. I told him that I felt that he was making the biggest mistake in his life.
