The point I consistently make, and which is consistently missed on this forum, is that God doesn't give you Christian leaders when you're willing to compromise and vote for anti-Christians. There are no Biblical examples of a people who were rewarded with a Godly leader because they were willing to sell their souls for political power in the mean time. The repentance comes first. The principles come first. Fear of God comes first. We get the options we deserve, and so long as those calling themselves Christian are willing to vote for pro-gay, pro-choice, pro-demon-worship Republicans then that's exactly what they'll continue to get. Why would God reward you for that?
"We have to vote for the pro-gay, pro-choice, pro-demon Republicans or else the bad guys will win!" is not how this works.
Quite literally all the time, have you ever read the Bible before? God forces Holy leaders on undeserving sinners constantly, for example
Jesus Christ.
God told the Jews in no uncompromising terms that Jesus was the messiah, and that those who did not obey him would be damned. And quite literally that happened as Jerusalem was destroyed, because it was packed with unfaithful sinners.
So, God does whatever He wants, and He doesn't reward us necessarily because we were faithful, but when He deems it according to His will. Our will does not matter in the slightest.
Thus, if God sends even a 10% Christian leader in this fallen disgusting world, you get down on your hands and knees and supplicate to Him for sending even a drop of holiness in a leader.
Who are we to judge what sort of leaders God choses for us?
Hence Paul says that those who rule are ordained by God, and that God will handle political affairs, and that Christians are to obey earthly laws until the arrival of the Kingdom. It's because the leaders we have are there for our salvation, it is part of this fallen world so that sinners may redeem themselves and be saved.
And a massive part of this salvation involves
forgiving those who are sinners, especially leaders who will even fight a little for you. This is the attitude of humility and reverence that God loves, and by doing this, THEN we become more pleasing to God, and He may reward us with better leaders in the future.
You are still a convert, and your understanding of Orthodoxy is only at the rational level. You do not understand the deeper applications of practical faith, it is about love. You must love this broken world and forgive its sinners, and understand that political progress happens as we forgive and love one another.
Rome didn’t become Christian under St. Constantine at all, he just made it legal to be a Christian. It became Christian under Emperor St. Theodosius, who made Orthodox Christianity the official state religion and dealt with all others as second-class faiths that could be practiced to various degrees according to how much damage doing so did to Christian society. He certainly didn’t practice “Big Tent Christianity” by promoting demon worship at rallies the way the RNC does.
I can see how incomplete your understanding is here; you miss the point entirely.
There would have never been a Emperor Theodosius without Emperor Constantine.
In God's divine wisdom and Love, He gave the people the leaders they needed at the time. Constantine, who barely knew anything about Christianity, who had scores of concubines and wives, who executed his first son because he was tricked by a false accusation, was the leader chosen by God for a specific time and place in order to advance God's will.
It didn't matter that Constantine was a sinner. All of us are sinners, focusing on sin makes no sense. What mattered was that Constantine had faith, and was able to act on that faith; God decided on him for that purpose just as God decided on St. Paul and so many other sinners who were turned into Saints.
We are not in control of this world, and Christ did not say "Only love those who are perfect." No, he said to love the sinner, love the enemy, and be perfect as our Father who art in Heaven is perfect.
When you internalize this logos, voting for Trump is an easy choice.
