The concept that culture and religion often get tangled together in confusing and often harmful ways is not a new one to me. But how Cleveland presented it made me more aware of the ways I more or less unconsciously buy into thinking a certain cultural aspect is "gospel." I grew up in Mexico as a missionary kid, and when the Christians there pray, they pray aloud - all together, and very passionately. This can come across as chaotic and annoying to outsiders. I was pretty used to it, but when my grandparents visited us, they tried to change how the people prayed. They emphasized one person leading the others in prayer instead of everyone praying at once as they saw fit. I came to see the collective prayer model I was so used to as wrong, and that it "hindered the Spirit." Would the Holy Spirit of the Almighty God be "hindered" because more than one frail human being was praying to Him at the same time? I'm not trying to bash my grandparents for doing this. They genuinely thought the way the Mexicans prayed was flawed and were trying to help them (though looking back, I can now see this was misguided). This was a case of culture getting confused with religion. I don't think God cares how we pray, as long as we fear Him.
Cleveland also talked about how to eliminate cross-cultural divides. People need to have meaningful interactions with others who differ from them, and not just coexist together. Relationships are the key to breaking down barriers. A few years ago, I was at a party with my family. I saw a very pretty girl there (pretty, as in haughty, mean, and probably wouldn't like me, obviously). We eventually ended up at the same table and tentatively started talking to each other. Turns out she had also been nervous about talking to me, and wondered if I would like her! She wasn't haughty at all, but actually pretty cool. If we had never talked to each other, both of us would have been stuck in our false assumptions. We were in the same place, but that in itself wasn't going to break any barriers. We would have just continued to watch each other, unsure if the other was too -blank- to approach. We had to engage in meaningful interactions in order to overcome our prejudices.
