90% of those who believe in BoD aren't interested in the rare case of a catechumen who dies before Baptism, but use it as a weapon to undermine EENS dogma.
But see those who are opening the door to the possibility of that One Catechumen supposedly dying without the Sacrament of Baptism (but still obtaining Salvation) this would then lead automatically to the idea that
anyone could potentially skip past the Visible Sacrament, because there’s an invisible option available too.
It’s opening the door to these exceptions that is causing the problem in the first place. Like when the smoke of Satan entered into the Vatican.
As far as BOB is concerned, say in the case of St Emerentiana. We need to maintain the importance of Sacramental Baptism, so it would make more sense then to believe that Emerentiana did in fact receive Water Baptism at some point
before her death, and not to assume she died without it.
Again, it’s all about maintaining the absolute necessity of Baptism by Water and The Holy Ghost, as Christ and The Church has always taught us.
