If Peter caving in front of the Jews counts, then yes
Some thoughts on your valid point, and some thoughts as to Tam's question.
Your post rightly shows the Twelve's earlier empowerment was no longer.
And Peter appears to have had issues with simply standing his ground at times.
And then there is the case of Apollos; a man "mighty in Scripture" and yet, at the same time "knowing only" so much, as he had obviously been in need of knowing some things "more perfectly" or, much more fully informed.
There was a brother years ago who had once had a worldwide books and tapes based ministry.
He had had a real zeal to get out his understanding of the Scripture to as many people as possible.
He invested just gobs of his own money towards all that.
One day, he heard a message on the gospel of our salvation.
Completely threw him.
A very humble man; he decided to look into it.
With his same characteristic zeal.
He now sends that all over the world.
Two things stand out...
Despite his great, earlier zeal, he had been wrong.
Why?
Where was God that He would allow not only such a waste of time and money, but on preaching a gospel that did not make His Son's FINISHED work the "light on an hill" it is meant to be?
In a silent Heaven; that's where.
Satisfied that Paul finished his coarse; the full revelation of the Mystery in written form and then some.
The above brother was simply in need of someone PROPERLY pointing him to the Scripture.
The other thing that sticks out?
His willingness to be a true Berean when he first heard what at first had appeared radical to him.
His willingness to hear the thing out; not prove himself the enemy so many prove themselves despite their illusions they are anything but.
But his is not how all are...
Even within the so called "Mad" of some...
To point out a thing to such is to find one is now considered their enemy.
