Acts 15:9 “And put no difference between us and them, purifying their hearts by faith.”
“Us” are the Jews and “them” are the Gentiles. Peter is saying that when “we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they” (verse 11).
Salvation eliminates our social, racial, gender, and religious differences. Every Christian who has ever lived, is living, and will live are perfectly equal in God’s eyes.
No socialism or postmodernism is necessary.
Yet we do not often treat each other as equals. There is still a hierarchy among Bible-believing Christians (which is, itself, a hierarchy to differentiate between those who follow biblical teaching and those who do not).
We put pastors on pedestals and act like church “visitors” are somehow not “like us” because they are “new.” We ignore or chastise Christians who disagree on minor doctrines.
I know I do this as well, because I am not perfect. I judge and am judged.
I pray that I exhibit more grace when dealing with fellow believers, and unbelievers as well.
