"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 spoked by the mouth of all his holy prophets since the world began." (Acts 3:19-21).
Once again, there is no message of Christ dying for our sins, being buried, and being raised on the third day: The Gospel. You will search Acts in vain trying to find Peter and the other Disciples preaching this Gospel. The Kingdom Gospel, yes, the Gospel of the Grace of God, no. The Kingdom Gospel does not contain the message of salvation in Christ's Finished Work on the Cross.
As a matter of fact, you won't find that message until after Acts 9. That's because that Gospel was given TO PAUL, BY JESUS CHRIST>Not Peter and the Other Disciples, because it wasn't part of the Gospel of the Kingdom. BTW: Peter and the Other Disciples received the power of the Spirit on the Day of Pentecost. I think they KNEW what they were to preach.
Do you ever kind of wonder why those silly guys (Matthew,Mark,Luke and John)bothered to write at all?
You're just blind, then. The Gospels are shot through with references to all of those things you say don't appear.
In John 1, the Baptist refers to Jesus as follows: he saw Jesus coming toward him, and said, "Behold, the Lamb of God, who takes away the sin of the world!". (John 1:29) Any Jew would have understood this to mean one who would be killed as a propitiation of sins.
In all of the Gospels Jesus quite clearly states that he will be arrested, beaten, killed, and on the third day rise again. See, e.g., Luke 18:32-33.
To say that none of this was stated prior to Acts 9 is quite simply false. Your whole attempt to differentiate between what Jesus preached (as if it were wrong, or a wilful deception aimed at misleading the Catholic Church....) and Paul's "corrected" version is quite simply wrong. False. Maybe even a lie.
Perhaps your obvious dislike of Catholicism is at fault for your mistake. Where dealings with Catholics are concerned, I'd suggest that a little humility on your part would not go amiss -- it would certainly make for a refreshing change, if nothing else.
