Bloodfire, I agree so
much with what TexasGirl posted - especially this.....
The effects of sin.... are bad.
It's difficult for me to think "what would Jesus think" because it's not like He's in seclusion now and not able to see - for goodness sake, He sees more than you and I do, because He also sees people's evil intents and knows the sinful thoughts of those who never act out. Add to that the fact that He knows the end from the beginning, that He exists outside time.....
I'm interested in this part of your initial question:
full of legalism and strange doctrine and what wd He think of the Trinity?
Well, given that He is OF the Trinity, that to me is an odd question. As to the rest of that, He knows us more than we know ourselves, and He knows how given we can be to legalism and strange doctrine when we are not in the Spirit.
Jesus did express some surprise in certain circumstances while He was on earth. Here's one:
As He spoke these things, many came to believe in Him. 31 So Jesus was saying to those Jews who had believed Him, "If you continue in My word, then you are truly disciples of Mine; 32 and you will know the truth, and the truth will make you free." 33 They answered Him, "We are Abraham's descendants and have never yet been enslaved to anyone; how is it that You say, `You will become free'?" 34 Jesus answered them, "Truly, truly, I say to you, everyone who commits sin is the slave of sin. 35 "The slave does not remain in the house forever; the son does remain forever. 36 "So if the Son makes you free, you will be free indeed. 37 "I know that you are Abraham's descendants; yet you seek to kill Me, because My word has no place in you. 38 "I speak the things which I have seen with My Father; therefore you also do the things which you heard from your father." 39 They answered and said to Him, "Abraham is our father." Jesus said to them, "If you are Abraham's children, do the deeds of Abraham. 40 "But as it is, you are seeking to kill Me, a man who has told you the truth, which I heard from God; this Abraham did not do. 41 "You are doing the deeds of your father." They said to Him, "We were not born of fornication; we have one Father: God." 42 Jesus said to them, "If God were your Father, you would love Me, for I proceeded forth and have come from God, for I have not even come on My own initiative, but He sent Me. 43 "Why do you not understand what I am saying? It is because you cannot hear My word. 44 "You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies. 45 "But because I speak the truth, you do not believe Me.
The sentence above that I highlighted to me shows Jesus like this -

- and then He has an idea -

- OHHHH , you are of your father the devil, THAT's why!
And before anyone rushes in to accuse me of blasphemy here, let me say that this is part of the human condition, not seeing everything, not understanding everything at once, and that Jesus was human when He walked on this earth. God in
carnate.
so nobody thinks Jesus will come down and scorn the churches and make them change?
Oh, absolutely He will judge, the Bible is clear on that. But you are not talking about that, I know. He
does speak to the churches and sometimes even "scold"s them. I know, because He's used me to do it. Generally in my experience, these kinds of things are spoken to the leadership in private. And as for making them change, I don't see Him doing that. He doesn't
make people change - it's not His M.O. He is after our hearts, not our unwilling obedience. He will not even change our hearts unless we are willing to cooperate.
blessings in Him
