I'm comfortable with this.
It's heretical to say that someone can be saved without Baptism. Even in the hypothetical case of BoD, the Sacrament of Baptism remains the instrumental cause of justification, operating through the
votum. I have repeatedly explained to BoDers how they must formulate BoD theory in order to avoid heresy, but most of them have refused the non-heretical formulation out of pride.
I don't believe in BoD because I believe that the character of Baptism is essential to the grace conferred, that membership in the Church is necessary for salvation, that there is no being "within" the Church without being a member of the Church, and because we cannot be adopted children of God and thus enter into the inner life of the Holy Trinity without God recognizing us as His sons ... due to the imprint of His Son's character in our souls.
I'd be much less uncomfortable with a BoD that also posited reception of the character of Baptism.
