Maybe - maybe not (John 6:66)
And, at the time of His speaking, the Church had not been established. That wasn't accomplished until Jesus was crucified, dead, buried, risen, ascended to the throne of the Father, and the Holy Spirit given.
Again, a logical non-sequitor,
1. Scripture does not indicate the elapsed time between Pentecost (When the Church was established) and Philip's preaching in Samaria (Acts 8) or Peter's visit with Cornelius (Acts 10) resulting in the conversion of his household to the faith.
2. And the Jews who made up the original Church are not equivalent of the Jews who did not follow Jesus. There has bee Judaism starting from the giving of the Law at Sinai. They are not who we commonly refer to as "the Church" since they were not followers of Jesus.
You are conflating a multitude of concepts.
And this has nothing to do with the OP.
You will need to do better than deny what the scriptures I have provided are teaching brother.
Why would Jesus say He has come to save the lost if no one was ever saved by Him preaching the Gospel?
Why would Jesus instruct people to do something with the Church and it’s members that did not exist?
For the Son of Man has come to save that which was lost.
“What do you think? If a man has a hundred sheep, and one of them goes astray, does he not leave the ninety-nine and go to the mountains to seek the one that is straying? And if he should find it, assuredly, I say to you, he rejoices more over that sheep than over the ninety-nine that did not go astray. Even so it is not the will of your Father who is in heaven that one of these little ones should perish. “Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. But if he will not hear, take with you one or two more, that by the mouth of two or three witnesses every word may be established.’ And if he refuses to hear them, tell it to the
church. But if he refuses even to hear the church, let him be to you like a heathen and a tax collector.
Matthew 18:11-17
How can Jesus send out His Apostles to save the lost, but no one is ever saved?
And when He had called His twelve disciples to Him,
He gave them power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease. Now the names of the twelve apostles are these: first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; Philip and Bartholomew; Thomas and Matthew the tax collector; James the son of Alphaeus, and Lebbaeus, whose surname was Thaddaeus; Simon the Cananite, and Judas Iscariot, who also betrayed Him. These twelve Jesus sent out and commanded them, saying: “Do not go into the way of the Gentiles, and do not enter a city of the Samaritans.
But go rather to the lost sheep of the house of Israel. And as you go, preach, saying, The kingdom of heaven is at hand.’ Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.
Matthew 10:1-8
again
And the Scripture, foreseeing that God would justify the Gentiles by faith,
preached the gospel to Abraham beforehand, saying, “In you all the nations shall be blessed.”
Galatians 3:8
You claiming a logical non-sequitor, in the face of the many scriptures I have provided
Is not going to cut it brother.
The ecclesia, the called out holy nation of God, the Israel of God, the Church began with Abraham and the covenant the Lord Jesus made with him.
