In the West, such prayer came to be restricted to souls in Purgatory, which idea has "ancient roots" and is demonstrated in early Church writings.
Di Barat, doa semacam itu kemudian terbatas hanya bagi jiwa-jiwa di Purgatorium, yang idenya memiliki "akar-akar kuno" dan terkandung dalam tulisan-tulisan Gereja awal.
