There will always be some difference in the words, this is true, but that also means that the truth in the teaching will be less powerful, and this leads to fewer people who will be able to gain higher wisdom or enlightenment status. So a reason you see so much negative around some spiritual groups is that some of the essences in the teachings have been lost now.
Buddha did say his teaching would start to decline 500 years after he left the physical realm, so yes even we try our best, it is extremely difficult to enlighten to his teachings today
Like that Jewish parable:
It is told that in every generation there are times when hope threatens to leave this world. At such times, the Baal Shem Tov, the great Jewish mystic, would go into a secret place in the forest. There he would light a special fire and say a holy prayer speaking the long-forgotten most sacred name of God.The danger was averted and hope stayed alive.
In later times when disaster threatened, the Maggid of Mezritch, his disciple, would go to the same place in the forest and say, “Ribono Shel Olam, Master of the Universe, I do not know how to light the fire, but I can say the prayer.”
And again the danger was averted and hope stayed alive.
Still later, his disciple, Moshe Leib of Sasov, would go to the same place in the forest and say, “Ribono Shel Olam, Master of the Universe, I do not know how to light the fire or say the prayer, but I found my way to this place, and that must be enough.” And it was. Hope stayed alive.
And later when Israel of Rizhyn needed intervention from heaven, he sat in his chair with his head in his hands and say, “Ribono Shel Olam, Master of the Universe, I no longer know how to light the fire, nor how to say the prayer, I can’t even find our way to that place, but I can tell the story and that must enough.” And it was.
And it still is. As long as stories are told, hope stays in the world.
