My position on the the cornerstone in scripture is that God is most definitely saying that the person of Jesus Christ is the cornerstone. I have not said I believe he is not. The question you have raised is "when" is he the cornerstone. You say it is when the apostles were chosen in Luke 6. You do not say how that series of events made him the chief cornerstone. Nothing about the physical birth of Jesus Christ informs us that he is made the cornerstone of the church. It is the events of his second birth when he became the cornerstone. This is the context of Acts 4:11. Peter refers back to Psa 118 and informs the Jewish audience, who are the rulers and teachers of Israel, that it is the confirmation that he has indeed fulfilled that prophecy at his death, burial, and resurrection. It is the single event that changed all history going forward and secures the kingdom of God. The cornerstone is in the broader context of the kingdom of God of which the church represents the spiritual part. The apostles and prophets with their special gifts are connected foundationally with both. Acts 4:11 narrows it down. Peter said that Jesus Christ was set at nought of YOU builders. (referring in context to this generation of guilty rulers)
Acts 4:11 This is the stone which was set at nought of you builders, which is become the head of the corner.
The earthly ministry of Jesus Christ concerns his earthly ministry and fulfilling the Abrahamic and Davidic covenants he has made with Israel. This kingdom he has come to establish is after the model of Moses in the wilderness where there were 12 heads and 70 elders. These offices he has filled with these disciples are kingdom offices and the church is built on them. They are said to be gifts to the church and were commissioned before the beginning of it.
27 Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore?
28 And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.
29 And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive an hundredfold, and shall inherit everlasting life.
That is either true or not. You be the judge according to how you believe words.
I am going to quote an OT passage concerning Jesus resurrection being a birth (he is the firstborn from the dead) and the head of the church at the same time.
6 Yet have I set my king upon my holy hill of Zion.
7 I will declare the decree: the Lord hath said unto me, Thou art my Son; this day have I begotten thee.
8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.
It is important to read whole context of Ps 2.
Acts 13:29 And when they had fulfilled all that was written of him, they took him down from the tree, and laid him in a sepulchre.
30 But God raised him from the dead:
31 And he was seen many days of them which came up with him from Galilee to Jerusalem, who are his witnesses unto the people.
32 And we declare unto you glad tidings, how that the promise which was made unto the fathers,
33 God hath fulfilled the same unto us their children, in that he hath raised up Jesus again; as it is also written in the second psalm, Thou art my Son, this day have I begotten thee.
34 And as concerning that he raised him up from the dead, now no more to return to corruption, he said on this wise, I will give you the sure mercies of David.
35 Wherefore he saith also in another psalm, Thou shalt not suffer thine Holy One to see corruption.
Read all the context and ask yourself what is Paul trying to prove with this quote of Ps 2 in the present dispensation. How does this square with your view?
JD, you are free to hold whatever prophetic framework you choose, but your position does not change the textual sequence Scripture actually gives. My point is simple and remains unchanged:
Jesus identifies Himself as the cornerstone during His earthly ministry, before His death and resurrection.
That is not my interpretive system , that is Jesus’ own application of Psalm 118.
1. Jesus applies Psalm 118:22 to Himself before His resurrection.
Matthew 21:42 is explicit:
“Jesus saith unto them… The stone which the builders rejected…”
He applies the rejected‑stone prophecy to His own person during His earthly ministry.
That alone establishes the cornerstone identity before the resurrection.
Your position requires that He cannot be the cornerstone until after resurrection.
Jesus’ own words contradict that.
2. Acts 4:11 is not about “when He became” the cornerstone.
Peter is not defining the moment Christ became the cornerstone.
He is identifying the same rejected stone Jesus identified earlier.
Acts 4:11 is a vindication, not a creation.
The resurrection vindicates the rejected stone.
It does not create the stone.
The cornerstone existed in prophecy (Psalm 118),
was identified in ministry (Matthew 21),
and was vindicated in exaltation (Acts 4).
That is the sequence Scripture presents.
3. Psalm 2 does not teach that Christ “became” the cornerstone at resurrection.
Psalm 2 is about royal enthronement , the public declaration of Sonship and kingship.
Acts 13 applies Psalm 2 to the resurrection as public confirmation, not as the moment Christ became the Son or became the cornerstone.
You are merging categories that Scripture keeps distinct:
Begotten (public enthronement)
Cornerstone (Messianic identity)
Foundation laying (apostolic constitution)
These are not the same act.
4. The apostles were constituted in Luke 6 , that is the beginning of the building.
Luke 6:13 is the moment Christ lays the foundation stones:
“He chose twelve… whom also He named apostles.”
Ephesians 2:20 identifies these men as the foundation of the assembly Christ promised to build.
Foundation laying is the beginning of building.
Pentecost is the empowering of what was already formed.
Your position requires the foundation to be laid after the cornerstone is set.
Scripture presents the cornerstone first (Psalm 118 - Matthew 21),
then the foundation (Luke 6),
then the vindication (Acts 4).
That is the order.
5. Your kingdom‑framework does not change the textual facts.
You are free to interpret the apostles as kingdom officers, or to connect Moses’ pattern to Christ’s ministry, but none of that changes the cornerstone sequence Scripture gives.
Your system may require Christ to “become” the cornerstone at resurrection.
Scripture does not.
The summary
Jesus identifies Himself as the cornerstone before resurrection.
Peter identifies Him as the same cornerstone after resurrection.
Psalm 2 concerns enthronement, not cornerstone identity.
Luke 6 is the laying of the foundation stones.
Pentecost empowers what Christ already built.
Your position is permitted as your personal interpretive framework,
but it does not align with the textual sequence Scripture presents.
