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.

Where did you come up with the idea that it was not faith in Christ? That right there is an excellent example of how the Calvinists twist other peoples words, and why your arguments are frequently useless.
What ever gave you the idea there is any such thing as apostolic succession or an "apostolic church "? Or a pope? or a priesthood?
Catholics believe it because Rome tells them it is true..but it is found no where in the foundational writings on the NT church.. That is the sola that the catholic church follows
Sola Ecclesia Romanus
Only the Church of Rome is the Rule of Faith
Not worth an answer, just demonstrably false.
Maybe we Catholics over stress this, but it seems to me that the disagreements among the differing schools of thought which all claim to be "Scripture Alone" makes this the only possible conclusion. On the finer matters of prevenient grace and of the saint's participation, if any, in his salvation, it seems that the hermeneutic dominates, NOT Scripture Alone.
Me, myself, personally, I prick up my ears when anyone says "obviously". Usually it is not so obvious unless you share the speaker's assumptions.
