You are certainly quite mistaken about that.
What's wrong with just accepting the approved part of La Salette ("devotion towards the Blessed Virgin under the title of Reconciliatrix commonly called of La Salette") and not receiving a "Secret" condemned by the Church?
Oh well then enlighten me, it wouldn't be the first time I was wrong about something, which ones do you accept? Which ones have you found personally beneficial? Which if any devotions promoted in these apparitions do you practice?
