Vatican Press Office vice-director Burke, announced on Monday that a meeting took place in the Casa Santa Marta on Saturday, April 2, between Pope Francis and the Superior General of the Society of St. Pius X.
We went to the Vatican information site and couldn't find it. The Vatican news website is the worst website ever made, but fortunately we have Rorate Caeli.
Rorate says that they, "learned it was a very positive meeting."
