It is a statement of basic doctrine to combat heresies and unify

As heresies or falsehood arise, things are added, not because there was something wrong in it, but because they are a convenient reminder

Your Church promised to not remove a single word at the 7th council.

It is you who wants to remove the Filioque

No the filioque is a total heresy. Nowhere in the scriptures. Nowhere in the Early Fathers.

At the 7th ecumenical councils, the creed was achieved. Your church promised To NOT amend it.

The Filioque is added from authoritative sources

The creed is not "achieved"

Which one?

You have no idea of what the purpose of the creed is

Which authoritative source?

The final authority of the roman see

Circular way of thinking....

In the Early Church, where is the authoritative source?

Something coming from the Church fathers is not an authority, since there were heretical Church Fathers

In the Early church, you have either Peter or his successors as final authority

That is, those who have the final word

It seems that you think, as I have mentioned earlies

That there is some magical year from which there are no authoritative statements

Can you tell us exactly what year and why?

Is it the year 300? 400? 401?

So the filioque doesn't come from the scriptures. It doesn't come from the Fathers. So, from where?

Only the Roman Church?

What does it mean that "it comes from the Scriptures"?

are you aware of where the consideration of something as Scripture comes from?

Are you a former protestant?

Are you aware that being a Father of the Church doesn't make what you say authoritative?

So what is authoritative according to the Roman Church ?

Not the scriptures, not the Fathers

So what?

What Christ declared to be Authoritative

Not any "Bible" or "Fathers"

But the Church

Because as you show now, there are heretical Fathers of the Church

It seems you love the words "Fathers"

No.

And hate "of the Church"

You have a list of authoritative Fathers who aren't heretical. @Mozalbete ⳩

So we agree the filioque isn't rooted in the Early Church. It comes exclusively from the Roman Church?

The papal primacy is off topic

The moment you say "Fathers who aren't heretical", you concede that being a Father does not give you authority
