The Armor of God is a spiritual concept:
[10] Finally, be strong in the Lord and in his mighty power. [11] Put on the full armor of God, so that you can take your stand against the devil’s schemes. [12] For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. [13] Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. [14] Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, [15] and with your feet fitted with the readiness that comes from the gospel of peace. [16] In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. [17] Take the helmet of salvation and the sword of the Spirit, which is the word of God.
[18] And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people.
It’s about prayer, not attacking “flesh and blood.” It’s about changing hearts and minds.
And it doesn’t apply at all to Trump, as he lacks truth, peace, righteousness, faith in God, or knowledge of His word or gospel. His spiritual warfare has been very prominently for the other side, using conservative/reactionary grievance politics to bring Christians over to his beliefs, rather than the other way around.
That said, there is a difference in pointing out the concepts in our handbook and talking about Christians in general. And Christians, in this case particularly the American Evangelical variety, have very much supported violence. That said, they also do push “rule of law,” which has a lot more to do with the negative reaction here.
To answer the OP: It seems to me that there is backlash, but they don’t necessarily connect it to Trump. Many want to excuse him. But they still consider the sedition a bad thing. Hence why some will try to say it was Antifa or something.
Among my Facebook friends, at least, I have noticed a much lower amount of enthusiasm for Trump than 2016, but that was true even before the election, let alone the sedition. I saw maybe one post trying to connect Trump with Christianity, and that was a post containing content originally by one of the Duggars, pushing the “he’s fighting against religious persecution” angle, and this was pre-pandemic (but still pushing people to vote Trump, so part of election season).
Since the sedition, I have seen one person push Trump’s “call for unity” nonsense that he cried after being caught, and one person comparing the coup to BLM with a stupid meme, but that’s about it. On the other hand, I did actually see some “let’s move on” posts post election, but before the sedition.
I wouldn’t say there’s some huge backlash, but I would bet that a lot of that decreasing approval rate is coming from Christians.
And there is a move among Republicans in general in the South. There were much more defections from the Republican Party in North Carolina than from the Democratic side. And, given the South’s culture, I would expect that most of those consider themselves Christians.
Oh, and pretty much all my friends or popular people I knew in high school (again, most of them claiming to be Christians) seem to be against the riots and Trump. But I notice that in my generation or younger in general around here.
