Paul never call the body of Christ saints sheep
As has been stated, that doesn’t matter.
Jhn 10:16 And
I have other sheep that are not of this fold. I must bring them also, and they will listen to my voice.
So there will be one flock, one shepherd.
Jhn 21:15 When they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “
Feed my lambs.”
Jhn 21:16 He said to him a second time, “Simon, son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “
Tend my sheep.”
Jhn 21:17 He said to him the third time, “Simon, son of John, do you love me?” Peter was grieved because he said to him the third time, “Do you love me?” and he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “
Feed my sheep.
Who was Peter sent to in Acts 10? Where was Peter in Gal. 2:11-14? What does Peter say?
1Pe 2:25 For you were straying like sheep, but have now returned to the Shepherd and Overseer of your souls.
1Pe 5:2 shepherd the flock of God that is among you, exercising oversight, not under compulsion, but willingly, as God would have you; not for shameful gain, but eagerly;
1Pe 5:3 not domineering over those in your charge, but being examples to the flock.
What else does Jesus say?
Mat 25:32 Before him will be gathered
all the nations, and he will separate people one from another as a shepherd separates the sheep from the goats.
Who compromises the sheep? People from “all the nations” who are his followers. Who compromises the goats? People from “all the nations” who are not his followers.
So what does Paul say?
Eph 2:11 Therefore remember that at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands—
Eph 2:12 remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world.
Eph 2:13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.
Eph 2:14 For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility
Eph 2:15 by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace,
Eph 2:17 And he came and preached peace to you who were far off and peace to those who were near.
Eph 2:18 For through him we both have access in one Spirit to the Father.
Eph 2:19 So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God,
Eph 3:4 When you read this, you can perceive my insight into the mystery of Christ,
Eph 3:5 which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit.
Eph 3:6 This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.
Eph 3:7 Of this gospel I was made a minister according to the gift of God's grace, which was given me by the working of his power.
Eph 3:8 To me, though I am the very least of all the saints, this grace was given, to preach to the Gentiles the unsearchable riches of Christ,
Eph 3:9 and to bring to light for everyone what is the plan of the mystery hidden for ages in God, who created all things,
Eph 3:10 so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places.
Eph 4:11 And he gave the apostles, the prophets, the evangelists, the shepherds and teachers,
Eph 4:12 to equip the saints for the work of ministry, for building up the body of Christ,
What do shepherds do? What is the body of Christ then that is being built up by these shepherds?
There has always been one church, one body, one flock, one gospel.
