You make so many assumptions against the written Word. According to the clearly written text of Hebrews, the New Testament Church did not exist until after Christ
What Hebrews text are you talking about? I have already demonstrated from the scriptures that it did.
According to the clearly written text of Ephesians 4, Christ did not establish the key functions of the church until after His ascension: prophets, pastors, teachers, or evangelists.
Jesus was the prophet, pastor, teacher and evangelist for the newly-minted church. After he ascended, others filled those roles as new churches were formed. Note that all those roles were connected to the local churches, not to some nebulous invisible entity.
According to the clearly written text of Acts 1, the indwelling of the Holy Spirit was a prerequisite to the Great Commission. No Covenant + no indwelling + no spiritual gifts = no NT church. Christ is still building His church that God adds to as people are saved. Acts 2:47.
That it did, in John 20:22
And when he had said this, he breathed on them and said to them, “Receive the Holy Spirit.
This was indwelling, prior to the Great Commission, before Pentecost.
It was also empowered with gifts. The disciples cast out demons, remember? The Head of that church also healed, raised from the dead, calmed the sea.
Acts 9 doesn't say that Saul sought membership in a religious institution. To join one' self with others is a common saying that means to come into company of another person or persons. You are adding church membership into the text. We should not form our doctrine based on assuming language into the text that isn't there.
When one seeks membership in a church, he is expressing the desire to join the disciples who congregate there. That's what Paul did and that's what I meant.
"I will build" (οἰκοδομέω, οἰκοδόμος), is in the future tense. The future tense corresponds to the English future, and indicates the contemplated or certain occurrence of an event which has not yet occurred. I don't see how you ignore the word "will" in the text. It is speaking of a future event. Your reference, when read in its entirety & kept in grammatical context, speaks against your position. You still haven't explained how your NT church existed under the Old Covenant apart from the all of the necessary elements of the New Testament. It didn't.
Jesus did exactly what he said he would--build his church. He had already established it. Now he would build it. Today, we might say he grew his church.
You would do yourself a great favor if you sat down & read Hebrews 7:15-10:20 without the assumptions or denominational bias.
I confess that I have biases. That doesn't mean they're wrong. They were not pulled out of thin air.
I am biased toward defining a New Testament church by what it does. Only the local church is equipped to carry out the Great Commission.
To argue for the idea of a Universal church is to argue for an entity which just is. It does nothing. Never meets. Never fellowships. Never evangelizes. Never spends a dime to spread the gospel. Never takes an offering. Never teaches its "members." Never baptizes anybody. It just is.
There was a song a few years ago called "Short People Have No Reason to Live." My next song will be "The Universal Church Has No Reason to Be."
In addition, if it exists, it is filled with people who believe error.
