I highly recommend Fr. Chad Ripperger's book,
The Binding Force of Tradition, if you are confused about what and when to believe priests, bishops, cardinals and even popes on statements of doctrine.
This book will help all the faithful understand what is truth and what is not, how to judge levels of truth and revelation and how to apply the Tradition of the Church to various subjects.
Seriously, if all Catholics read this book, they would be no longer confused about media statements and various sermons.
Please get it and read it.
This book will give you great peace of mind.
