Purgatorial societies are Roman Catholic Church associations or confraternities which aim to assist souls in purgatory reach heaven. The Catholic doctrine concerning purgatory, the condition of the poor souls after death (particular judgment), the communion of saints, and the satisfactory value of our good works form the basis of these associations. In the modern Church this role is fulfilled by the Purgatorian Archconfraternity which is run under the auspices of the Transalpine Redemptorists.
