My point is that scripture does not actually state the antichrist enters the Church. That particular belief originates due to a conflation of Thessalonians' mention of a "
man of lawlessness" or "
lawless man," and the antichrist. Perhaps it should not be
assumed the two are the same person. Modern futurists typically conflate the AoD
and the MoL with the antichrist but I cannot recall ever reading anyone making the case for that conflation. Everything falls apart if 1) the AoD is not a person, and 2) none of them are the same individual.
I did not say or ask about the antichrist ever
being the Church
(even though that was the basic argument of the Reformation against the RCC). I asked about this premise the antichrist would enter
in the Church.
Where does scripture state the antichrist
entered the Church?

Again, where does scripture state the
antichrist entered the Church?

Yeah, I'm not seeing it. The entrance is inferred because of the departure but the possibility the "they" did, at some point, believe Jesus is who scripture says he is has to be ignored in order to assert that position. Matthew 7, for one, tells us there are many poseurs in attendance. Where does scripture say the antichrist infiltrated the Church? What my Bible states about the antichrist is very specific and very limited. Where does scripture state the antichrist comes from among those who left the Church? John and his original first century readers knew the last hour had come because many antichrist had [already] come, including the one antichrist they were anticipating. That's what 1 Jn. 2:18 states. The following verse, verse 19, states "they," the many antichrists "went out from us," implying those antichrists had once been members of the congregation (but not necessarily the Church) and implies those individuals' departure proved they "never belonged to us."
So I get where you say they had previously been in the Church, but had they previously been in the Church as antichrists? To answer in the affirmative begs certain questions, such as, "If they never belonged the why was their entrance permitted in the first place?" Was proper oversight failing? When John says they went out from "us," is he referring to the congregation, or is he referring to the apostles (since it was the apostles who sent others out to preach, teach, establish new congregations, etc)? Is John implying the apostles had failed in their discernment?
Yes, an antichrist is, among other things, someone who denies Jesus was sent by God. How then would someone enter, or infiltrate, the Church not believing Jesus is from God. One possibility is that the "us" in the relevant text is "us Jews," since John is the most Judaic NT author. Given the overlap between the OT's qahal (=assembly) and the NT's ecclesia (=those called out) it is reasonable to infer John is talking about Jews attempting to Judaize the gospel and deny the divinity of Christ. Jesus is not from God, he did not come in the flesh, and the Father and Son are denied,
Whoever the "us" refers to, it's odd that they'd enter the Church denying the identity of Christ and later leave. I am more inclined to read the text to imply they had professed some degree of intellectual assent but had never been changed by God. They were not actually membersof the Chruch, parts of Christ's body.
This morning, I met with a younger man I am discipling and we discussed how he came to know Jesus. He recounted his upbringing, observing at a very young age the congregations were full of hypocrites, full of Christians but not believers, the latter being people who actually practiced their faith. I, personally, would not use the terms he used but his point is valid. Not all who call themselves Christians are actually Christians..... but the pew warmers usually profess Jesus came from God in the flesh and don't deny the Father and the Son.
Exactly. It directs us to reason through its revelation and it does so for the purpose of out understanding.
And the point I believe four out of five of us can agree upon is that the "last hour" happened two millennia ago and is not still happening or yet to occur. Whatever else it may be, it was the last hour of an age that has come and gone because, whether read literally or figuratively, hours do not last millennia.
