If you want to try to start the body of Christ in Acts 2 and anywhere else besides Act's 9, you will come across many conflicting and contradictory verses. Here is a few for you.
Hebrews 2.3-5
How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?
So apparently, there was a great salvation that was FIRST spoken by the Lord. Matthew-John. And then was CONFIRMED unto them that heard him. The church in the begging of the book of Acts. These things have ALWAYS been in prophecy. They have always been prophesied. Hence, the word SPOKEN. Now if something began with the Lord and was confirmed in Acts 2. How can Paul say that the body of Christ was NEVER made known until revealed to him from Christ???
Let's compare Peter's message in Acts 2 and 3 with Paul's message and you WILL see they are not the same thing.
Acts 3.21
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.
Acts 2.15-17
For these are not drunken, as ye suppose, seeing it is but the third hour of the day. But this is that which was spoken by the prophet Joel; And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
Peter says, this thing going on over here in the book of Acts is THAT which was SPOKEN BY THE PROPHET JOEL.
Now that those facts are established. Let's look at Paul. And you will know for sure that the Church in Acts 2 is NOT the body of Christ. The text won't allow it.
Eph 3.1-9
For this cause I Paul, the prisoner of Jesus Christ for you Gentiles, If ye have heard of the dispensation of the grace of God which is given me to you-ward: How that by revelation he made known unto me the mystery; (as I wrote afore in few words, Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel: Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power.
Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
If what Peter says in Acts 2 WAS MADE KNOWN from the beginning of the world. And Paul says what he preaches WAS NOT MADE KNOWN since the world began. Then they are NOT the same thing. You know good and well these verses have competing wisdom and say two different things. This is why rightly dividing the word of truth is crucial. It's not dividing truth from error. It's dividing truth from truth. Everything in the bible is truth. So if Peter contradicts Paul, you need to study to find out why.
Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body’s sake, which is the church: Whereof I (Paul) am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God; Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints: To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:
Paul says his message is a mystery hid in God. Acts 2 cannot and never will be the body of Christ. The text won't allow it.
