They do not believe in God but gods so they contradict the apostle's creed. The nicene creed is where they really contradict. Most protestant's believe in both creeds as long as catholic church is interpreted as the universal church.
I'm sorry but I'm not following how the quote from Isaiah is relevant. As for where you said they were evil, you said the "distort, lie, and cover up". THose are pretty strong words, especially in the context you put them. The fact that you put "lie" in there shows that you meant they intentionally misrepresent things. If you're uncomfortable with the accusation, then apologize and retract it, but don't go pretending you didn't make it. For my part I'll happily admit that the leap from "distort, lie, and cover up" to "evil bastards" was entirely my own.
Ok I retract calling them "liars" since many lie, but few are professionals. I'm well aware that there are many whom have been decieved unknowingly. I believe that the head of the mormon church along with a few others are decieving people on purpose. When you call yourself a teacher, you have to be sure of yourself. That is why nothing I say should be taken as truth unless it's fully backed up by yourself, so that I do not end up lying. I've found that people lie because of ignorance. But to be a valid excuse this cannot be the false ignorance of over confidence. Anyways the Isaiah verse is important since he prophesies the Messiah.
Isaiah 43:10-12
"You are my witness, says the LORD, my servants whom I have chosen To know and believe in me and understand that it is I. Before me no god was formed, and after me there shall be non. It is I, I the LORD; there is no savior but me. It is I who foretold, I who saved; I made it known, not any strange god among you; You are my witnesses, says the LORD. I am God, yes, from eternity I am He; There is none who can deliver from my hand: who can countermand what I do? Thus says the LORD, your redeemer, the Holy One of Israel: For your sakes I send to Babylon; I will lower all the bars, and the Chaldeans shall cry out in lamentation. I am the LORD, your Holy One, the creator of Israel, your King."
Compare with
John 13
12
So when he had washed their feet (and) put his garments back on and reclined at table again, he said to them, "Do you realize what I have done for you?
13
You call me 'teacher' and 'master,' and rightly so, for indeed I am.
14
If I, therefore, the master and teacher, have washed your feet, you ought to wash one another's feet.
15
I have given you a model to follow, so that as I have done for you, you should also do.
16
Amen, amen, I say to you, no slave is greater than his master nor any messenger 7 greater than the one who sent him.
17
If you understand this, blessed are you if you do it.
18
I am not speaking of all of you. I know those whom I have chosen. But so that the scripture might be fulfilled, 'The one who ate my food has raised his heel against me.'
19
From now on I am telling you before it happens, so that when it happens you may believe that I AM.
20
Amen, amen, I say to you, whoever receives the one I send receives me, and whoever receives me receives the one who sent me."
And
John 6:45
"It is written in the prophets: 'They shall all be taught by God.'"
John 6:69
"We have come to believe and are convinced that you are the Holy One of God." Jesus answered them, "Did I not choose you twelve? Yet is not one of you a devil?""
The Holy One refers to Isaiah
