Every denomination has some teaching or doctrine that we would not agree with.
How would you explain the difference between an
incorrect teaching
and
a heretical teaching...?
IOW,,,when does an incorrect teaching become heretical?
Great questions, but I would have to start with a definition of “the church”, when it was clear from Jesus’ teachings that the devil was going to sow seeds of false Christianity in “the world”, and that his true disciples (the “wheat”) would be “growing” in the same “field” right along with these “weeds” (Matthew 13:24-30; 36-42).....so how were we to tell the difference?
Getting into the details of this parable, we can learn some important aspects in our identification of the “weeds”. The particular “weed” used in Jesus’ illustration was assumed to be “Bearded Darnell” which was a common (and poisonous) pest in the Middle East among farmers, because in the early growing stages, it was very difficult to tell them apart from genuine wheat. In fact some farmers would sabotage a neighbor’s crop with this weed to spite them.
So when the farm workers asked their Master if they should remove the weeds, he said no!...in case they were to uproot the wheat along with the weeds, so they were to “grow together” until the “harvest time” when the reapers would be able to recognise the weeds (which were now very different to the wheat in appearance) and gather them first, and burn them in the fire to destroy them before they could produce more seed. Only then would the farmer gather his wheat into his storehouse.
Now with that in mind, when were these weeds sown? Jesus said that it happened “while men were sleeping”....so this might mean the death of the apostles, who were acting as a restraint even back then when some were trying to introduce false ideas. (2 Thessalonians 2:7)
The other kind of ‘sleeping’ that the Bible speaks of is spiritual sleep, not being awake and prepared for the things Jesus spoke about. (10 virgins)
In any case, it indicated that false Christianity would result, and that is was to take root as soon as the apostles passed away. Nothing would then restrain this tide of apostate thinking, turning “the church” into something Christ said he was never a part of. (Matthew 7:21-23)
So, looking into the history of “the church” from the second century onward, what do we see...?
We see a very corrupt system which was responsible for much bloodshed...even torture...all in the name of Christ, who never sanctioned such a thing in the first place. (Matthew 5:43-44)
Jesus would be with the “peacemakers”...”the pure in heart”.....those who did not teach doctrines that he never mentioned....and ”the meek” he said, “would inherit the earth”....not heaven.
So what “the church” became after the death of Christ and his apostles, was foretold, and it should come as no surprise that the power it took on in those early centuries corrupted the daylights out of it.
Jesus said “by their fruits” we would recognise his true disciples, who would be following through on his teachings, being hated and persecuted just as Jesus was by the very ones who claimed to worship the same God as he did. (John 15:18-21)
The “heresies” according to the church, were those against what it taught, when they themselves, like the Pharisees before them, were guilty of “teaching the commands of men as doctrines”. (Matthew 15:7-9) The heretics were so busy pointing fingers at those who dared to challenge their doctrines, that they had completely lost the plot and did what the Pharisees before them had done...they murdered those who dared to correct them, but not before torturing a confession out of them for justification. Would Jesus have done that? That is the ‘mother church’ who gave birth to many daughters, all as corrupt as herself because they took the core of her teachings with them...none of which were scriptural.
The Jews to this day, deny Jesus as the Christ, and Christendom to this day has followed in their footsteps.....teaching all manner of falsehoods and even placing God’s son on equal footing with his God and Father.....breaking the first Commandment. (Exodus 20:3)
Heretics will not recognise their heresies because to them, they are truth....and “a man convinced against his will, is of the same opinion still”....The truth that Jesus taught “divides” people as it should. (Matthew 10:34-36) God’s word is the truth that lets us come to really “know” God and his Son. (John 17:3; Hebrews 4:12-13)
So it is a deep question, but one that the Bible answers for those whose minds and hearts are not closed.
