The KJV, NKJV, the NIV, and the NLT are not causing confusion
The Bible is where we get our Doctrine.
The foundational truth of God's word must be built on Christ. I do not see false doctrine in the NIV, the NKJV, or the NLT in context to the Person of Christ.
You say we are supposed to speak the same thing as the bible says so?
1cor 1:2, 10-12-13
2 To the church of God which is at Corinth, to those who are sanctified in Christ Jesus, called
to be saints, with all who in every place
4 I thank my God always concerning you for the grace of God
which was given to you by Christ Jesus, 5 that you were enriched in everything
by Him in all utterance and all knowledge,
6
even as the testimony of Christ was confirmed in you,
7
so that you come short in no gift, eagerly waiting for the revelation of our Lord Jesus Christ,
8 who will also confirm you to the end,
that you may be blameless in the day of our Lord Jesus Christ.
9
God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord.
Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and
that there be no divisions among you, but
that you be perfectly joined together in the same
mind and in the same judgment.
What is that "same thing"?
We must read on
10 Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and
that there be no divisions among you, but
that you be perfectly joined together in the same mind and in the same judgment. 11 For it has been
declared to me concerning you, my brethren, by those of Chloe’s household, that there are contentions among you.
what contentions ?
12
Now I say this, that each of you says, “I am of Paul,” or “I am of Apollos,” or “I am of Cephas,” or “I am of Christ.”
13
Is Christ divided? Was Paul crucified for you? Or
were you baptized in the name of Paul?
