“All human beings are God’s children”
The Ponovizer Rov, Rav Kahanaman zt’l used to visit South Africa a lot as he had relatives there and the Jewish community there has mainly Lithuanian roots.
He once visited the Chofetz Chaim zt’l after one of these visits, and the Chofetz Chaim asked him about how the black people in south Africa were doing and that he had heard they were being persecuted.
Rav Kahanaman asked the Chofetz Chaim what his interest was in south african affairs.
The Chofetz Chaim replied that they are also G-d’s people and he needs to be concerned about their welfare.
