Don Guanella was firmly convinced that the press had an important role in spreading the truth and charity. And don Guanella made use of it, committing much of his time and even his scarce money to it.
We wanted to collect all of Don Guanella's editorial production and the result was 5 large volumes, which form Don Guanella's OPERAOMNIA. Volume VI will collect his nearly 4.000 letters that have so far been found
In the Opera Omnia, on the one hand we have the Operettas, addressed to everyone, from the simplest to the most learned, with an eminently popular slant, where examples, parables, even suggestive images abound.
Another important patrimony are the Writings for his two religious Congregations.
