No it is not; I merely explained the teaching of the Apostolic Church.
It is still your own personal interpretation of the scripture. Your decision to follow the Roman Church's teachings without question is based upon your own personal interpretation of the scriptures that the Roman Church uses to justify their dogma.
So regardless of how you interpret it, YOU interpret it. It is YOUR interpretation. It may coincide with the teachings of the present Roman Church, but when it comes down to brass tacks it is your interpretation.
I find nothing in 1 Pet 1:20 which prohibits people from coming to an independent conclusion on the meaning of scriptural passages, but then that is my interpretation.
Where would I find the "official" Roman Church position on the interpretation of 1 Pet 1:20? And what procedure did the Roman Church authorities use in coming to their own personal interpretations of the passage?
