ESV 1 Thessalonians 2:14 For you, brothers, became imitators of the churches of God in Christ Jesus that are in Judea. For you suffered the same things from your own countrymen as they did from the Jews, 15 who killed both the Lord Jesus and the prophets, and drove us out, and displease God and oppose all mankind
First Thessalonians 2:15 points out something important when thinking about Christ, Christianity, and the secularist agenda. Secularism aims not to eliminate Christianity completely, but to relativize it so that it loses its message and distinctive voice to be considered among the many others. This is another way of eliminating Christianity, by forcing it to become and claim something that it is not, one view of reality just as true as any other. That is a small but deadly shift from a statement I would agree with: Christianity is a view of reality that could be and should be heard and considered just as any other view. That’s not to say it is equally true as all other views. It is to say it has at least equal right to be heard and considered as true just like other views, religions, and worldviews have that right if someone cares to voice them.
This passage tells us that those who were driving out Christians displeased God and “oppose all mankind.” That’s an interesting way of putting opposing Christianity and the spread of the gospel. To oppose Christ and Christianity is to oppose mankind. This is the Paul and God’s view of opposition to the gospel and Christianity. Most secularists think they are doing good to mankind, humanity, and society by pushing Christianity to the side in particular issues like education, parenting, gender issues, abortion and life issues, sexuality and marriage debates, etc. I am grateful that they care for mankind and care for society and the future but at the end of the day, when you oppose God, you oppose the good of mankind. Why? The Bible at this point assumes that God is good for mankind and therefore Christ and the spread of the gospel is good for mankind. To oppose Christ, Christians, and the spread of the gospel, is to oppose the good and glory of mankind which is to be found in God and God’s gospel in Christ. So don’t oppose all of mankind by not opposing Christ and his mission. If you are not a follower of Christ, one of the best things you could do for mankind is to let Christians speak with all the distinctiveness of their message and worldview as you would desire for your own worldview. To oppose that is to oppose all mankind, and worse, to displease God.
