The following quote is from Pope Bl. Pius IX's declaring St. Alphonsus Liguori as a Doctor of the Church:

Can anyone provide me with a link to the papal document Qui Ecclesiae Suae?

I thought it would be an easy thing to find, but I was mistaken.

  • No, you're right. For this Q, the buck stops here. Other avenues we can try while continuing Google / library search: 1) Contact the Vatican; 2) Email websites that specialize in Vatican documents such as papalencyclicals.net (I sent the inquiry to them); 3) Wait until @Geremia picks it up; he has proven quite resourceful.

  • @GratefulDisciple Yes; Geremia might know where this document is hiding.
