And just as importantly, were we given a method of identifying them?
The warnings were given especially by Christ and the Apostles.
2 Thessalonians 2:3 Let no one seduce YOU in any manner, because it will not come unless the apostasy comes first and the man of lawlessness gets revealed, the son of destruction. 4 He is set in opposition and lifts himself up over everyone who is called “god” or an object of reverence, so that he sits down in the temple of The God, publicly showing himself to be a god. 5 Do YOU not remember that, while I was yet with YOU, I used to tell YOU these things?
What more do you want? A list of the exact teachings that would be dragged in? Scripture gives us the correct teachings to compare any other teaching to, do you need to be spoon-fed?
Is it not enough that al these Apostate teachings, from the trinity on, have come from False religions and have been applied to false gods?
There are so many warning not only to come out of the world empire of false religion but also not to bring it's teachings into the Christian Congregations. warnings which, like all previous warnings were ignored.
(Revelation 18:4,5) And I heard another voice out of heaven say: “Get out of her, my people, if YOU do not want to share with her in her sins, and if YOU do not want to receive part of her plagues. 5 For her sins have massed together clear up to heaven, and God has called her acts of injustice to mind.
(Jeremiah 51:6) “FLEE out of the midst of Babylon, and provide escape each one for his own soul. Do not be rendered inanimate through her error. For it is the time of vengeance belonging to Jehovah. There is treatment that he is paying back to her.
(2 Corinthians 6:17) “‘Therefore get out from among them, and separate yourselves,’ says Jehovah, ‘and quit touching the unclean thing’”; “‘and I will take YOU in
(Isaiah 48:20) Go forth, YOU people, out of Babylon! Run away from the Chal·de?ans. Tell forth even with the sound of a joyful cry, cause this to be heard. Make it to go forth to the extremity of the earth. Say: “Jehovah has repurchased his servant Jacob.
(Isaiah 52:11) Turn away, turn away, get out of there, touch nothing unclean; get out from the midst of her, keep yourselves clean, YOU who are carrying the utensils of Jehovah.
(Jeremiah 50 “Take YOUR flight out of the midst of Babylon, and go forth even out of the land of the Chal·de?ans, and become like the leading animals before the flock.
(Jeremiah 51:45) “Get out of the midst of her, O my people, and provide each one his soul with escape from the burning anger of Jehovah.
(Zechariah 2:7) “Hey there, Zion! Make your escape, you who are dwelling with the daughter of Babylon.
Don;t forget also that the Revelation scripture I quoted before also shows that those who wished to go down that "broad and spacious road" were to be allowed to to be allowed to grow as long as God wanted to allow them to.
That is still the case, though now Christ has arranged the preaching work to encourage those who wish to follow him to do so correctly, which again fits in with Revelation 22:11. The choice is ours. We must make that choice carefully with only one question in mind. What do God and Christ want us to believe?
(Revelation 22:11) He that is doing unrighteousness, let him do unrighteousness still; and let the filthy one be made filthy still; but let the righteous one do righteousness still, and let the holy one be made holy still.
Yes, we were warned will in advance, and told that it was to be left unchecked.
Scripture is very clear about what the true teachings are, and gives us the information we need for life. (John 17:3) This means everlasting life, their taking in knowledge of you, the only true God, and of the one you sent forth, Jesus Christ.
That scripture alone gives us the first clue to identify one major false teaching - the trinity. "the one you sent forth", not the one who came forth, the one who God sent.
