Founded by decree as a Sui Iuris Catholic Church by His Holiness, Patriarch Dom. Luis Fernando Castillo Mendez. 

Address by H.E. Cardinal Alfons Stickler on June 20, 1992 at the Annual General Meeting of the Latin Mass Society.
Your Movement has Legitimacy in the Church. The first idea I will communicate with you is that you can be sure that your movement has full legitimacy in the Church. Some have said that we are not legitimate. This is not true because, if you remember article 4 of the Liturgical Constitution, the Council Fathers explicitly said all the venerable rites have to be preserved. Some people say this is valid for all the other rites, with the exception of the Roman Latin rite. This is not so. Because article 4 says: all the rites legitimately recognised.
