The Church of Christ is the Church we read about in the NT. The scriptures are not interepreted by each congregathin of the Church. Rather if a congregation is not worshiping God as we read of in the scriptures,they are not pleasing to God.
Once Christ died he made a new covenant with Man. He made sure that everyone both Jew and Greek would be included in God’s plan.
God makes it clear that man has a choice to learn of him and either accept or reject Christ. With the exception of the thief on the cross,we read of amny accounts of the teachings of Jesus and his preaching and teaching. We tells us what to do to be saved. We can’t earn our salvation as it is a free gift. However their are caveots to claim your gift. We must hear the truth,beleive, confess, repent and be baptized for the remission of sins,and we are added to the church. Nothing more,nothing less. We then must go and tell the world of God,so each may hear and accept or reject their saviour.
You see it is not up to us to determing how to please God. God wants us to worship him the way he tells us to.
As an example the old law ( before the death of Christ),God demanded animal sacrifices. God no longer accepts these offerings. His new covenant asks us to do other things.
The Apostles lived and died,but the Church that was established at Christs death,lives today. Read of Pauls letters to the 1st century Church. He reminds them to do as God wishes,to be his Diciples.
