Jude is going to change his tagline to "Only the church is a Roman"?
That is the sola that the catholic church follows
Sola Ecclesia Romanus
Only the Church of Rome is the Rule of Faith
Catechism of the Catholic Church
85 "The task of giving an authentic interpretation of the Word of God, whether in its written form [Scripture] or in the form of Tradition, has been entrusted to the living, teaching office of the Church alone. Its authority in this matter is exercised in the name of Jesus Christ."47 This means that the task of interpretation has been entrusted to the bishops in communion with the successor of Peter, the Bishop of Rome.
