Is an mv user a heretic simply because they use an mv? Not necessarily. BUT if they use one with full knowledge of the differences and history of the manuscripts - and still reject the truth, because it will rock the boat, go against their family, friends or church, or some other reason where they choose to compromise, then I truly believe they are compromising and sinning. It is one thing not to know the truth on this issue and to use mv's ignorantly - it is quite another thing to deliberately choose a watered down position or compromising position because standing for the truth is not something they are willing to do.
