Actually, I think the burden is on you to prove that this was speaking of an organized church which was headquartered in Rome or even in Jerusalem. Assemblies of Christians met in homes, catacombs, fields, etc. - wherever they could. So talking about knowing how to behave in the "house of God" could NOT have meant a physical "church" building but a metaphor for the spiritual house of which is made of all believers who are living stones of which Peter spoke of. Paul also reiterated this thought in I Corinthians 3:16, "Don't you know that you yourselves are God's temple and that God's Spirit dwells in your midst?". The Body of Christ is intended to BE the pillar and support of the truth - the truth revealed to believers by the Holy Spirit and codified in Holy Scripture. We ALL have that duty.
So another vote for the First Baptist Church of Ft. Worth?
