As for the totalitarianism of what is commonly known as Christianity or Christendom consider the Crusades which @Episkopos also mentioned who chose to fight fire with fire instead of following the Way of Jesus.
"And when his disciples James and John saw this, they said, Lord, wilt thou that we command fire to come down from heaven, and consume them, even as Elias did?
But he turned, and rebuked them, and said, Ye know not what manner of spirit ye are of.
For the Son of man is not come to destroy men's lives, but to save them... Luke 9:54-56
Someone is always telling you or me or that other guy to come to his church because his church is the best one and to believe his, or his church's, version of truth, for surely it is the correct one. That started long ago now with simpler even kindly words, but the pressure is increasing now for harsher words and ways against anyone not conforming to certain ecumenical and politically correct standards [rather than God's]. Who will choose to stand with Jesus then...?
Must we lose our heads? The Baptist did!
Must we be physically crucified? Jesus was!
Must we be stoned? Stephen was!
Is one of those choices going to be too hard for us to bear it? If it is, then is perhaps the fear of man in us greater than the Love God in us? Perhaps some of us are Not really then... born again or born from above?
The pressure is already being applied as we see with the rejection of the scriptures or the diminishing importance of the scriptures or the changing meaning of words we use regarding God and the things of God... to something more politically correct to replace the unchangeable Word of God... although they may still name it the Word of God!
People say they follow the Bible, but what most of them follow as we see from our societies are men who have bent or twisted Bible verses to fit their own programs and doctrines... instead of seeking God's kingdom and righteousness first so as to receive God's understanding of that which God anointed men to write.
People speak of the Holy Spirit, but in most church gatherings in most places the Holy Spirit is not allowed to lead and sometimes not even to abide. In the olden days the signs read, "Irish need not apply", but very soon or even now they might read "Holy Ghost manifestations not allowed.] In most "church" meetings man's programs prepared by men determine who is allowed to participate at any given time from the first 'hello' to the last 'goodbye' of each meeting. Who are these men who set the programs? Are any or all of them part of a totalitarian leadership hindering even God Himself with their programs and aimed against anyone who is not completely with them!
"And John answered and said, Master, we saw one casting out devils in thy name; and we forbad him, because he followeth not with us.
And Jesus said unto him, Forbid him not: for he that is not against us is for us.
Luke 9:49-50
But now even Jesus himself is not among them. He was forbidden long ago though they still may speak his name... as if they knew him.
If they are moving closer together, are they not most often moving away from God because God does not meet their membership requirements?
If they are moving farther apart is it not most often in an 'each to his own' direction which also is moving away from God who is Not the author of confusion?
Where is God?
Not in any totalitarian move where by following their leaders many [perhaps most] people are moving closer to each other in man's unity, which he names: ecumenism... but it is not God's unity. No, they, including undoubtedly some seen here on this forum, are often more concerned with attacking the non-conformist anyone already set apart as a "cultists" simply because they won't embrace the totalitarian [usually known as the Christian] way. God is not in that way!
No...to all of this say some honestly, who really love God! That "some" are likely included in the very few passing through the needle's eye or entering the strait and narrow gate, are they not?
Members of churches and their leaders call their ways Christianity, but too we ask seriously where Jesus is to found in it! They program God out of their 'worship' services; they program in only those pre-approved by the totalitarian leaders (kings as per Hosea 13:9-11 called now: ministers, pastors, evangelists, priests) who meet their own requirements as if they knew better than God how to lead. [They don't ever trust the Holy Spirit to actually lead!] Now anyone not with their program who opens his mouth is asked to leave. but to go where? Most real better alternative places, the truly better choices are diminishing as the supposed Christians who never had more than a façade covering them drop out of sight when any real obstacle appears before them... or they simply join the growing ecumenical crowd following the totalitarian ["Christian"?] way.
The secular government is with them in seeking to eliminate the opposition even though the opposition unbeknownst even to their ministers is quite often God, Himself.
"And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
And he said unto the disciples, The days will come, when ye shall desire to see one of the days of the Son of man, and ye shall not see it.
And they shall say to you, See here; or, see there: go not after them, nor follow them." Luke 17:20-23
