Did Jesus and Paul Give a sermon to the same disciples over and over

The priesthood of all believers is the mututal participation of everyone in the fellowship. There is no clergy/laity separation within the Body of Christ nor a hierarchial headship based on ones gifts. Christ is the Only Head of His Church where no man lords over another. We renounce the bondage of the institutional church system that makes some Christians feel that they have to meet in specific place (usually a building), on a specific day (usually Sunday) and have only specific people (usually someone with a title) minister to a passive audience, God's Word without their input. We desire to see a fully functioning priesthood of believers where we can stir one another in love and to good works. Heb. 10:24
