It's not up to laymen to decide that. Using your private judgement to determine whether the Church is right or not when it teaches is private judgement and protestant to the core.
I don't use my judgment to determine whether the Church is right or not, I use it to determine whether I am being preached
a gospel besides the one that the Church preached before. And if so, I let the false preachers be anathema.
And I don't base my procedure on my private interpretation of Gal 1:9, but on infallible teaching of the Council of Trent. Above, I quoted the Council of Trent stating that the teachings of the same holy Synod are to be used as
rule of faith, and asking me to use that same rule of faith to,
in the midst of the darkness of so many errors, more easily be able to recognise and to hold Catholic truth.On the other hand, I might argue against you
ad hominem: If you take your own approach seriously, why don't you abstain from posting? You are using your own protestant private judgement to tell me what a Catholic should do or omit.
And another comment
ad hominem: If I listen to those who you call apostles, then why do you bother me when they preach freedom of speech, salvation for all men (excepting arms dealers), ..., and finally celebrate Dr. Martin
private interpretation Luther's anniversary.
You find the true Church, and then you accept what the true Church teaches. There is no other way. "Dogma" as a rule of faith is useless unless you know who has the rightful authority to pronounce it in the first place. You find the Church, and then you accept what She teaches.
All I find are neomodernists and other kinds of heretics. Not a single faithful shepherd with an apostolic mandate. But I also find written dogma definitively explaining content of the
depositum fidei.
