1 John 2:18-19 "Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have arisen; from this we know that it is the last hour. They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, in order that it might be shown that they all are not of us."
Here is why I say that they (antichrists) came from within us (the Church/Christianity)
Great passage. Thanks.
It can refer to Gnostic-type Christians (cf. 2 John 1:7; 1 John 4:3) who left the church because of it's (correct) insistence that Christ is in the flesh (Luke 24:39).
Believers need to be careful not to be deceived by the Gnostic/antichrist lie that Christ isn't in the flesh (2 John 1:7), and that believers won't forever be in the flesh. The Bible shows that Jesus Christ wasn't resurrected as a disembodied spirit, but in his human, flesh and bones body (Luke 24:39, Hebrews 2:17). That's why his tomb is empty (Matthew 28:6), and why he still has the wounds of the crucifixion on his resurrection body (John 20:25-29). And Luke 24:39 didn't stop being true once Jesus ascended into heaven. For he will remain forever the human mediator/high priest of believers (1 Timothy 2:5, Hebrews 7:24-26), in human flesh, just like they're in human flesh (Hebrews 2:17). And when he returns, he will still have the wounds of the crucifixion on his resurrection body (Zechariah 13:6, Zechariah 12:10-14).
Gnosticism mistakenly thinks that flesh is evil in itself, and that only that which is pure spirit can be good. But Jesus proves that flesh isn't evil in itself, for he has been made flesh (John 1:1,14, Romans 1:3, Luke 24:39), and remains wholly without sin (Hebrews 4:15). Genesis also proves that flesh isn't evil in itself, but was created by God as something very good (Genesis 1:31). Adam and Eve were flesh, for they were the progenitors of the human race alive today. And they were immortal before they fell into sin, for it was only their falling into sin which made them become mortal (Genesis 2:17). So Adam and Eve started out as immortal flesh. And so the future resurrection or changing of saved people into immortal flesh bodies like Jesus has (1 Corinthians 15:21-23,51-53, Philippians 3:21, Luke 24:39, Romans 8:23-25) will be God allowing them to partake of the original, immortal-flesh condition of Adam and Eve in the Garden of Eden before their fall into sin.
Also, beware of the more-general Gnostic lie that even the entire physical universe is evil in itself, and that only a purely-spiritual heaven can be good. For this lie is employed by Gnosticism to revile the Creator YHWH God as some sort of evil, tyrant, lesser god, whom Gnosticism says created the physical universe as a foul prison house for the free spirits of humans, whom Gnosticism says by some mistake fell from a purely-spiritual heaven into the physical universe and became trapped in fleshly bodies. No doubt the coming Antichrist will employ this lie as part of his utter reviling of YHWH (Revelation 13:6, Daniel 11:36). But Genesis shows that our physical world was created by YHWH as something very good (Genesis 1:31).
And the Bible shows that the whole plan of Creation wasn't that humans, who are both flesh and spirit (1 Thessalonians 5:23, Luke 24:39), would become purely-spiritual ghosts and float forever on clouds in a purely-spiritual heaven with God, but that God would become both flesh and spirit like man (John 1:1,14), and that God would ultimately come down out of heaven to live with man on a future, new earth (Revelation 21:1-4), just as God had walked on the earth in the Garden of Eden with Adam and Eve (Genesis 3:8). Also, on the new earth, saved humanity will be allowed to eat from the tree of life (Revelation 2:7, Revelation 22:2,14), just as Adam and Eve hadn't been forbidden to eat from it in their unfallen state (Genesis 2:9,16,17). So, with regard to saved people, God will completely undo the effect of the fall of Adam and Eve. Saved people will be able to live in an earthly, physical paradise forever with God (Revelation 2:7), just as Adam and Eve and their descendants might have done had not Adam and Eve fallen into sin.
So beware the Gnostic lie. Beware the Antichrist.

Some people consider this to be the RCC, I am undecided.
Note that the antichrist deception isn't the RCC, for the reasons given in the 2nd section of post 20.
