Trump has been paying lip-service to Christianity. As you state, he’s not for directing religion, but freeing it up to flourish as it can and should.
He addresses the issue of “Christmas”, and I think it’s far more than a charming thing to promise. It represents a respect for Christianity, our customs, and our traditions.
It hearkens back to better times when our culture was treasured. It’s about time!
And this seems to be a difficult thing for some people to believe. That getting Caesar out of the Christianity “business” (although keeping his Romans 13 role as a bully pulpit for what is good) is just what Christianity needs to show the whole world that it is much more than the “plain vanilla” of religion.
The idea that things should be any other way dates back to only a few hundred years into the early church.
Caesar offered his unmanageable kingdom up on a silver platter to the Christian church. The proper response should have been to offer advisors (as Daniel and others were in the Old Testament) but to also point out that the church was given to govern a heavenly kingdom and could not ever take over the operations of Caesar, this was not in the charter. The church presumed to be too much, and ironically became too little.
