Does the Bible say Christians should treat rich and poor people the same?
Yes. Scripture teaches that believers must not sort people according to their place in the social strata, but must treat one just like another. Love must be without dissimulation, or sincere and impartial. The book of James makes this principle plain, so Christians are not to show favoritism based on social status.
The teaching explains that believers are not to sort people out according to where they are in the social strata. Love has to be without dissimulation, and one person is to be treated just like another; the book of James makes this so plain. So the biblical standard rejects favoritism or social ranking. In the surrounding context, this call to sincere love stands alongside the command to abhor evil and cleave to good, rather than accepting the world's confused values.
