The Catholic Church developed the canon of the New Testament, a canon which is still accepted by all Christians. They determined which books went in and which didn't.
And why do Catholics then consider the Gospels superior to Paul's letters?
I think superior is probably the wrong term. I think it would be more accurate to say that Catholics do not show the preference for Pauline epistles that a minority of Protestants do.
And if the writings of Scripture are that likely to be subject to error,
Where have I EVER said that?
then why are the traditions of the Catholic church not considered to be so?
The Catholic Church has NEVER said this.
And my original response was that the WRITTEN Gospels appeared AFTER Paul was martyred and what was considered "common knowledge" was as likely to be wrong as it was right.
No. I'm answering yours. But I just saw that I got the post number wrong. It should have been post 2,618 not 2,816.
mm: And if the writings of Scripture are that likely to be subject to error,
wb question: Where have I EVER said that?
mm answer: In post 2816 2,618 where you said...... "And my original response was that the WRITTEN Gospels appeared AFTER Paul was martyred and what was considered "common knowledge" was as likely to be wrong as it was right."
