"I and my Father are one" (John 10:30)


Rember what was just said there in John 10:30 at the end of this discussion.  Yeshua and His Father are one. ,Paul tells us that Christ is the Head of the church. A unified Messianic church were both Jew and Gentle worshipped and praised God together is the church that Paul, died establishing in the name of the Father,  one body one church not like modern day splintered  denominations.

Many Pastors and theologian  claim that denominations are all part of one universal church theory, though they contradict one another. But is this how Christ and His Father are? When did the Father and Son ever disagree about what church people should be members of? or about how to worship God? or about the plan of salvation? or about the organization of the church?

When did the Father say to the Son: "I disagree with your practices, but it doesn't matter what you believe as long as you're sincere. We're all going to the same place, at least I hope we are, if Christ is your savior and the head of your life and you have confessed him as such and ask forgiveness for your sins and accepted him as your Lord. 

In what sense were the Father and the Son "one"?
