Are you saying that all Christians correctly interpret Scripture or only that small fraction that agree with you?And what language is "plain language"?
(Note: you need to research what Nicolaitanism really is before you attempt to paint the Church with that heresy or at lease attempt to substantiate your assertion.)
I’m saying that the face meaning of every sentence in the Bible is true, and that the only places where Christ used allegory are where he said that he did, and that his explanations to the disciples were for us, and that they are clear.
Allegory is rare in the Bible, and where it is used we are warned in the text, usually in advance.
A person of average intelligence will easily understand the Bible IF THEY WANT TO UNDERSTAND, and if they do not wish to understand, the Holy Spirit will help them become confused.
P.S. Nicolaitano has had a clear meaning in the Greek language for over three millenia. It has been used in various forms to deride tyranny of almost every kind.
