The problem is that in every church, in every time, Catholic or Protestant, there have always been good and bad members. Pointing out bad Catholics or Protestants doesn’t prove or disprove a particular church’s teachings. I think it would be better for all if Priests just taught the faith and didn’t get into the sins of Protestants.
I would say that your particular church didn’t exist, I think what that priest is saying is that there is no “one” Protestant faith, because they are so various.
Whether there is equality, I think as far as human dignity is concerned we are equal. But we are not all equal in what gifts we have been given, in terms of teaching and tradition. We have been given a greater depth and breadth, from Saints, Popes, and Holy Traditions which have been passed on since the first Christians.
This makes sense because the Catholic Church is much older and more widespread that any particular local denomination.
The Catholic Church does say they have the fullness of the faith, because the reformers did away with a large chunk of tradition, a large chunk of what the Apostles handed on to us up until that time.
There is a greater fullness, if you ever read the writings of the Saints and the Popes and Theologians through the centuries, all showing how God can work through his Church if we cooperate.
