The Church has two foundations: Jerusalem and Rome. Under the Roman Emperor Constantine some corrupt practices were allowed into the church. Various attempts to reform the church since then have led to denominations and divisions in the Body of Christ.
In our time the Holy Spirit is not just reforming but restoring His Church back to the Jerusalem foundation. This vision of the Church is at the heart of the ministry of the New Covenant Church. Here the leadership is not sitting on top of a pyramid.
