I've been commenting throughout the whole thread!
The gospel of the earthly restoration of the kingdom of Israel.
Both taught it and neither of them taught opposing views on that.
I'm wondering where Paul taught the restoration of the earthly kingdom of Israel. Certainly it wasn't his focus.
Paul taught about the Kingdom of God in heavenly places.
The gospel of salvation unto eternal life was due to the death and resurrection of the Lord Jesus Christ, and not by works of the law.
Both taught it and neither of them taught opposing views on that.
Neither taught an opposing gospel of either.
You make all these statements without any backup whatsoever.
Let's just assume you know there are works other than the works of the law.
Were they teaching repent and be baptized?
Maybe show where Peter says what one must do to be saved.
Were they preaching the same salvation? Really?
Could you address this, for instance.
Acts 3:19-21
Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord. And he shall send Jesus Christ, which before was preached unto you: Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
