Can churches ever agree with one another?


I appeal to you, brothers and sisters, in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought.  1 Corinthians 1:10
            There are certain degrees of agreement that churches can accept.
            It starts with Jesus – the son of God, who came to the earth to die for our sins, and his death on the cross was all we needed to begin a relationship with God.  It’s all about Jesus.  Next, the churches must all agree that all 66 books of the Bible are the inerrant word of God.
            After that, churches have freedom to express their faith differently—through music, teaching styles, leadership, organization, pews or folding chairs, communion once a week or once a month, baptism by sprinkling or full immersion, speaking in tongues, healing.  All these are preferences. 
Denominations can interpret the scriptures differently in some cases, with freedom to be who they want to be, but they cannot interpret Jesus differently or the parameters of sin outlined in the Bible.
If the churches correctly accept the real Jesus and the Bible, then after that, yes, the churches can come closer to unity.
