You would obviously agree that to render unto Caesar that which is his, and render unto God that which is His, is a spiritual truth to be honoured. The problem the church has these days is in discerning what actually belongs to each camp. Also, I believe there were many genuine Christians being led by their conscience to vote for Trump, thus giving to Caesar his due. They, while believing it their God given duty to do so, did not go so far as to align that duty with the idea that Trump is God's anointed servant and the saviour of the American Church. Nevertheless, they voted for someone they believed would better promote freedom to exercise their religious duty in rendering to God that which is God's. Any sane, sensible, observant Christian would have recognised the attacks that Satan, through the political, educational, legal and media apparatus, had made against family and the laws, and the people of God. Those voters, at least many of them, would have also recognised that only God can change hearts and minds, and that the voting for Trump cannot do that work. But it can do work in as much as Caesar is given authority and power to bring common sense back into American society, just as we would hope Caesar can do in Australia. Where I would draw the line, is not in refusing to give Caesar his due as you espouse, but in refusing to use Caesar or allow Caesar to give the church power which is outside of his perview. That is my greatest fear as far as the current American situation stands. That America would create an image to the medieval church/ state union as per the prophecy of Revelation 13. An image to the Catholic beast. That people voted for Trump doesn't bother me. What bothers me is the present relationship between church and state. The amalgamation between Caesar and God is purely a Roman Catholic concept, totally contradictory to the intents and beliefs of those founding fathers who wrote the constitution based on protestant principles that repudiated the Catholic mindset and dogmas of the dark ages.
