1 John 2:19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
This passage is commonly misread as to somehow prove that
anyone who apostasizes was
never a born-again Christian in the first place. However, that is a conclusion that is not justified from the wording of this passage.
First, of all this passage is describing certain false teachers (ie, "many antichrists" v18--those who deny the Father and the Son, vs 22-23; those who deny Jesus had come in the flesh, v. 4:3) who
may in fact never had been true Christians. However, the passage does NOT say that "
anyone who
ever leaves us shows that they were
never of us
at one time".
Also, even with these particular folks who left the passage
doesn't say:
"They went out from us, but they were
never of us; forif they had
ever at one time been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were
never of us." It simply says that
at the time these folks departed (and perhaps for an unspecified time before that), these "were not of us".
That true Christians
can depart from God is evident in Hebrews:
"Beware,
brethren (ie the same
'holy brethren' the author has been addressing; v.3:1), lest there be
in any of you an
evil heart of unbelief in
departing from the living God: (Hebrews 3:12).
This is consistent with: (1) Romans 11:18-22, in which Gentile believers (who "stand by faith") could be cut off like the unbelieving Jews if they did not continue in God's goodness; and (2) John 15:1-6 in which branches
in Christ could be cut off if they did not abide in Him and bear fruit; as well as many other warning about falling away, etc.
BTW--good point,
Thinkingstuff, about
1 John 2:24-25.
