20 In spite of all this, do not think, Venerable Brothers, that the Mexican hierarchy lost any opportunity or occasion by means of which they might do their part in calming popular feelings and bringing about concord despite the fact that they distrusted, or it would be better perhaps to say despaired of, a happy outcome to all these troubles. It is sufficient to recall in this context that the Bishops of Mexico City, who act in the capacity of procurators for their colleagues, wrote a very courteous and respectful letter to the President of the Republic in the interests of the Bishops of Huejutla, who had been arrested in a most outrageous manner and with a great display of armed force, and had been ordered taken to the city of Pachuca. The President replied to this letter by means of a hateful angry screed, a fact now become notorious. Again, when it happened that certain personages, lovers of peace, had spontaneously intervened so as to bring about a conversation between the President and the Archbishop of Morelia and the Bishop of Tabasco, the parties in question talked together for a long time and on many subjects, but with no results. Again, the Bishops debated whether they should ask the House of Representatives for the abrogation of those laws which were against the rights of the Church or if they should continue, as before, their so-called passive resistance to these laws. As a matter of fact, there existed many good reasons which seemed to them to render useless the presentation of such a petition to Congress. However, they did present the petition, which was written by Catholics quite capable of doing so because of their knowledge of law, every word of which was, moreover, weighed by the Bishops themselves with the utmost care. To this petition of the hierarchy there was added, due to the zealous efforts of the members of the Federation for the Defense of Religious Liberty, about which organization We shall have something to say later on in this letter, a great number of signatures of citizens, both men and women.
