Rome distinguishes two states of that same faith: it may stand apart from God's love and other pious works — as in many sinners — or be joined to love and good works.
Apart from love it is called dead and idle; joined to love it is living and effective.
Latin
II. Caeterum fides illa, vel a Dei dilectione, aliisque piis operibus separatim existit, ut contingit in multis peccatoribus; vel cum amore Dei, & aliis bonis operibus juncta est. Priori respectu dicitur mortua atque otiosa, posteriori viva & efficax.
