In this short talk, Michael Horton—professor of systematic theology and apologetics at Westminster Seminary California—talks about why there is no such thing, in the new covenant, as a “Christian nation” apart from the worldwide body of Christ. “The problem with Christian nationalism is not that some Christians are taking a biblical idea too seriously,” Horton says, “but that they are confusing America with Israel under the old covenant. From a biblical perspective, it’s actually heretical. It confuses the law with the gospel.”
