But even if you understood the gospel completely - that does not mean you'd believe it true.
Understanding is an aspect of knowledge, not a separate function. Asserting that the Holy Spirit is needed for such understanding fits well with an important element in your definition of a cult.
I am not accusing you of making such an assertion, but was noting that it is habitual for some Christians. Perhaps any truly effective definition of a cult must acknowledge that any religion may serve to engender cultist behavior in some individuals.
Better definitions have already been presented, however.
The anthropological/historical definition sees all religious groups as fitting the criteria. The orthodox Christian definition, on the other hand, limits usage to groups guilty of egregious errors in doctrine. Only the latter is a cause for substantial argument.
