Seventh Session has the canon that defines (condemns) salvation via faith alone aka a BOD:
CANON IV.-If any one saith, that the sacraments of the New Law are not necessary unto salvation, but superfluous; and that, without them, or without the desire thereof, men obtain of God, through faith alone, the grace of justification;-though all (the sacraments) are not indeed necessary for every individual; let him be anathema.
As of late, a BOD has been compared to "the other" Trent teaching on a Confession of Desire.
Sixth Session has the canon that defines (condemns) a Confession of Desire:
CANON XXIX.-If any one saith, that he, who has fallen after baptism, is not able by the grace of God to rise again; or, that he is able indeed to recover the justice which he has lost, but by faith alone without the sacrament of Penance, contrary to what the holy Roman and universal Church-instructed by Christ and his Apostles-has hitherto professed, observed, and taught; let him be anathema.
Interesting to note that *justification* via faith alone is condemned for one already baptized, yet BODers insist that faith alone aka a BOD rewards *salvation* for one unbaptized.
