Apparently in your haste to find arrogance you missed several things:
1) I left the Catholic Church and came back.
2) The Bible says that the Church is the pillar and foundation of truth: 1 Tim 3:15 in case I am delayed, so that you may know how to behave in God's household, which is the church of the living God, the pillar and foundation of the truth.
Since the only "Church" was the Catholic Church, that must be the one and only Church that Paul is speaking about.
To my knowledge, the church in Rome wasn’t the “head church” in the Church at the time Paul wrote that.
I’m a member of the Church, the one Christ founded. I’m not subservient to Rome.
Thank God for the Reformation, the season in the life of the Church that allowed Christians to return *home* to Christ.
