Yashayah kept it simple and plain unlike the abominable Church

Sealed Portion Ch 46:43

And these are the things that Yashayah taught unto the Jews at Jerusalem; and the words of Yashayah were plain and easy to understand. But because the people were so convinced that salvation came another way, even by the way that the leaders of the church had showed unto them, they could not accept the simple and plain words of Christ.
