PURGATORY occupies an important place in our holy religion: it forms one of the principal parts of the work of Jesus Christ, and plays an essential role in the economy of the salvation of man. What then is the work which we, members of the Church, have to do for the souls in Purgatory ? We have to alleviate their sufferings. God has placed in our hands the key of this mysterious prison: it is prayer for the dead, devotion to the souls in Purgatory.
