First off, there’s the treatment of religious deities that starts with their mythological backstory… which in their reality is fact, not mythology. T’Challa not only can step into the ancestral place, but even has a choice whether to stay. His ritual of entering the other side- burying himself under sand after drinking a certain herb, resembles ancient pagan practices where people perform various routines to meet a deity face-to-face. Amongst all the world religions that have false gods whom require works to earn blessing from, Christianity rather teaches about unconditional love that starts with Jesus taking our place on the cross. God’s final sacrifice proves that we have no need to follow rituals such as animal slaughter to earn our way into Heaven, it’s our hearts, not our actions, that the Lord is most concerned about. (1 Corinthians 10:31, James 2:14-26)
