This @PeterTurner's answer to What is the difference between a dogma, a doctrine, an infallible statement, an ex cathedra statement, etc.? opined
There are a few levels of Magisterial Teaching. Some people say there are 3 some people 4 and Wikipedia says there's 7, but I'll go with 5, the first two are infallible the last 3 aren't so much.
From her very beginning and through the centuries, the Church has had symbols of faith.1 One such symbol is the Apostles' Creed, rightly considered to be a faithful summary of the Apostles' teaching.2
Perhaps "levels of Magisterial Teaching" meant to say that there is a “hierarchy of truths” to which the believer adheres.3
Understanding it this way, the question is, according to the Catholic Church in her recent pronouncements, what is the order of truths to which the the believer adheres? Does this order correspond a new symbol of faith, a new Profession of faith?
Note, the best answer will be the one that references official documents.
