Spiritual heritage

I have sometimes thought that when Alma the younger speaks to the people of Zerahemla about “their fathers” who were delivered from the armies of King Noah that many of those hearing him we’re not descendants of that group. I realized today that when those groups came together and shared their histories and reacted to the experiences of the groups returning from their diaspora that they all said that heritage. He could just add well have spoken about those listening to King Benjamin was their fathers and spiritually it would be true for all the believers at least.
