The other day I was having a conversation with a Catholic who thought that someday women would be ordained and that Jesus did ordain women - she gave Mary Magdalene as an example (which I then asked “where are your sources?”).
I have heard that this cannot happen because the Holy Father has spoken about it (the authority has not been given to the Church to ordain women) and the Apostolic letter “Ordinatio Sacerdotalis”.
Now my question is not about the ordination of women, but how do we know that this is to be held as definitive? It is not dogma, per say, but truly a teaching of the Church. How do we know it is to be believed “de fide”??
There could be other examples - basically alot of teachings that have not been defined as “dogma” that are contained in Apostolic letters like “Humanae Vitae” or “Evangelium Vitae”. How are these “doctrine”? And how do we convince others that they need to adhere to the teachings contained in them?
