I have no idea when or where it came from. All I know is that I was somewhere listening to some teacher who had this drawing and I copied it because I thought it was a good visual aid.
The point is that false teachings are often very subtle because they cross back and forth over truth. All cults and false teachers have some truth in their teachings, which makes discernment of the utmost importance. Often it is the true parts of their teachings that draws people unwittingly into the false, not being able to discern where the line was crossed.
An example would be Mormonism when they speak of God, Jesus, salvation, atonement, etc. The words themselves can be true descriptions of Christian theology, but the Mormon definitions are not in accordance with Scripture and are false teachings, only picking up the truth of the words as they cross the line of truth.
Roman Catholicism has much more truth than the LDS, of course, because Rome is a true Christian faith which has added much aberration and heresy to burden the Catholic faithful. They actually have a truth line which makes the criss-crossing of it with their false teachings all the more difficult to discern.
It is important for every Christian to be continually in the Word of God so that the line we follow is the true path, and so that we will be able to recognize the false teachings whenever they cross our line.
