There are lots of things that I think the Latino culture in general has to offer to the mainline “Anglo” church. Things like a relaxed attitude toward time (do we REALLY have to apologize if the service is longer than one hour and fifteen minutes?), how to greet and acknowledge people, the value of family, etc.
Two of the biggest have been thrust on Hispanics here in the States, yet are major traits that the church as a whole needs. One is the ability to separate church and country. The Hispanic community has 14 different countries which have contributed significantly to its makeup, not counting the United States. There is a greater awareness that the church is larger than any one country.
The other major thing is the awareness of being strangers and aliens in this world. Not all Hispanics are aliens, yet there is a greater sensitivity to what that lifestyle really means. Some rebel against that feeling and that reality, just as some Christians seek to blend in rather than seeking to stand out. The church needs to be called back to the fact that we are all aliens, we are all foreigners, no matter what country we’re living in.
Those are the main things I see. Want to add to the list?
