Which word is that?
Incidentally, "mystery" does not mean "things Catholics believe, even though they make no sense."
There are other words that describe believing what makes no sense and contradicts the Bible.
In the New Testament, the word 'mystery' has specific meaning and refers to something very special and it isn't 3 n 1 or anything like that.
God is in Christ. And Christ is in the believer. Doesn't that make the believer God, too?

You are the one who contradicts the bible. To the trinitarian, there is no contradiction. Jesus is both God and Man. God exists in three persons, the Father, the Son, and the Holy Spirit. Accept these propositions, and the bible makes sense. Deny them, and you end up having to ignore, as you do, key portions of the bible, such as John's Doxology.

No. The paper is in the folder; the folder is in the briefcase. That doesn't mean that the briefcase is the paper. But the bible doesn't say God is IN Jesus. It says Jesus is God.

Yes, it does refer to something Paul says IS known. "or I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in." or "Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed," or "Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:"

Oh? How's this: "And to make all [men] see what [is] the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ" So, all things were made by Jesus. Hence, Jesus is not merely the man born of Mary, but predated all things. Do you know what you call one who creates all things? Who is eternal? You call such a being a god.
