The Church doesn't have time to condemn every error in the world, thus She teaches what one MUST believe. Logically, if something doesn't fall into the parameters (or contradicts) what one MUST believe, it is error. It could be innocent error, or it could be purposeful heresy. The intention is irrelevant; it's still error.
Baptism is required for heaven (article of faith)
Baptism = water + Holy Ghost (article of faith)
BOD = no water + Holy Ghost*
Ergo, BOD is not Baptism and cannot get one to heaven.
The only thing BOD can provide a soul is sanctifying grace (per Trent); it cannot provide heaven (logical conclusion).
*Theoretically.
