3 First of all, to be sure, with respect to the patronato of the Portuguese people in the East Indies, We have concluded a formal pact with the most faithful king of Portugal and Algerve. This agreement has removed the causes of dissensions, which had disrupted Christians for so long a time. These communities have been under obedience to apostolic vicars and prefects. We have decided to form them into dioceses with their own bishops to be administered by ordinary right. Therefore, by the apostolic letter, Humanae salutis , given on the first of September, 1886, a new hierarchy has been instituted in those regions, consisting of eight church provinces, namely, Goa as the patriarchal see, Agra, Bombay, Verapoly, Calcutta, Madras, Pondichery and Colombo. Furthermore, through the Congregation of the Propagation of the Faith, We will do whatever will be fruitful there for salvation and for the increase of faith and piety.
