A BOD Is salvation by faith alone.
So, that's a huge problem with BoD, as articulated by 99% of all BoDers. Basically what the vast majority claim is an "ex opere operantis" salvation, where people can work out salvation on their own and without the Sacraments.
St. Robert Bellarmine recognized this problem and thus came up with the formula that one receives the Sacrament "in voto", not that one does not receive the Sacrament, since even in BoD you MUST say that the Sacrament remains at least the instrumental cause of justification, somehow. Now that's a huge stretch, especially in case where people never heard of Baptism, i.e. for "implicit" desire, but at least it doens't contradict the necesity of the Sacrament for salvation.
Yet almost every single modern BoDer say that there can be substitutes for Baptism, and get sloppy and do not mean that there can be substitutes way of being justified by Baptism than via the actual reception of it with water. That latter is what might be acceptable in the context of Trent, but almost NOBODY out there articulates it this way.
So the end result is that most are Pelagians and believe in self-justification and self-salvation.
