I am not saying we shouldn’t criticize his policies if we disagree with him. I’m not saying we shouldn’t work to get others elected we agree with more. Our form of government gives us great power and responsibility, and we need to be responsible. What I am saying is that Christians who do these sorts of things publicly ought also to be following 1 Tim 2:1-2 publicly at least as much as they follow the other practices, since 1 Tim 2:1-2 is actually a written command of God. And even though many might be saying, “I already do those things in private,” even if you are, I certainly don’t see anywhere near as much giving thanks and prayers for President Obama in public by believers as I see vehement invective. This is how we lead by example as believers, and it is why people with influence are held to a stricter account (James 3:1). Maybe you are praying as much in private as you insult in public, but for those you have influence over, what are they seeing? What is done privately or what is done publicly? Jesus Himself said it would be better to have a millstone tied around your neck and be thrown into the sea than to lead one of His little ones astray.
I also believe that people who compare themselves to Christ and His rebukes of the Pharisees are missing that He rebuked the Pharisees directly, in person, not passively, in such indirect mass comments on Facebook. The language Christ spoke directly to them was a rebuke only after calling on them directly many times to repent.
Many would also say Martin Luther used far harsher language in criticizing leaders of his day than any believers today are using. Those people would be correct. However, in the same way that we cannot hold Luther and others of his day to our cultural standards today, by the same logic we cannot appropriate standards that were accepted in his culture and unilaterally claim they’re acceptable in our culture. One cannot have it both ways. At any rate, though I don’t have a primary source reference for this, I believe Luther had repented of having written too harshly of individuals.
Finally, here is a question for any professing Christian – which do you care about more? The U.S. Constitution, an excellent though man-made document, or the Holy Word of God, breathed by the Holy Spirit, a Word that cannot be broken? It seems to me we shouldn’t be compromising the Word for the sake of anything else, even the safety of the U.S. Constitution. If we cannot save the Constitution without breaking the Word of God, I’d have to say God cares more about us following His Word.
