would you donate to Copeland...and the like.

I DO NOT agree with Beckie as she is in error unless she is speaking of the words of the Jewish Apostle John.

Who is the liar, except the one denying that Jesus is the Christ? This is the antichrist, the one denying the Father and the Son.
1 John 2:22

i live in a Jewish community and know the Chabad rabbi who we just had shabbat dinner with recently.

They are lovely people - but they are antichrist for the very reason that Apostle John stated.
They also follow a dead antichrist who is called the 'Rambam' = Moshe ben Maimon.

This Rambam/Moshe changed the Torah to prevent Jews from seeing their Messiah.

The nation of Israel is in peril for they will soon embrace the Antichrist.

Which is why many are coming to Christ now.

Do you consider that John was writing to correct a particular problem or do you think that these books automatically accuse all non-believers in Jesus as anti-Christs?

We both know that only God knows the hearts of every person.
We also know that we are living in perilous times ever the more so in world history.
Jesus said that His Return will be as it were in Noah's day and time, whereby only 8 souls were saved.
Because of the Blood of Christ and outpouring of the Holy Spirit, there is Great Hope in the midst of great evil.
This Great HOPE is "Christ in you the Hope of Glory" = preaching the Good News of Salvation in Christ Jesus our LORD.

The spirit of antichrist is spreading rapidly throughout the world preparing the world for the coming of the wicked one.
Right now this antichrist spirit has saturated the minds and souls of Jew and Gentile alike.
This is where we are in world History.

But in accordance with your hardness and your impenitent heart you are treasuring up for yourself wrath in the day of wrath and revelation of the righteous judgment of God, who “will render to each one according to his deeds”: eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality; but to those who are self-seeking and do not obey the truth, but obey unrighteousness—indignation and wrath, tribulation and anguish, on every soul of man who does evil, of the Jew first and also of the Greek;
but glory, honor, and peace to everyone who works what is good, to the Jew first and also to the Greek.
For there is no partiality with God. Romans 2:5-11

Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour. They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us.

But you have an anointing from the Holy One, and you know all things. I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth.

Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
1 John 2:18-23

Keep lifting UP Prayer and Praise to the LORD and to be filled with the Holy Spirit.
