Jesus Himself addressed the church in Revelation 2 and 3. These seven churches are a representation of the whole. Shouldn't we judge ourselves against the admonition of our Lord Jesus Christ instead of creeds, sacraments, etc.? For instance does your church "sufferest that woman Jezebel?" Does your church "hold the doctrines of the nicolaitans?" Is your church "lukewarm", etc.? If we held fast to these admonitions then wolves like Rick Warren, Joel Osteen, etc. would be unemployed and ecumenical compromises with Islam and the Vatican would not be occurring.
