My dad said that Catholicism is a cult because it “controls you salvation.”
The Catholic Church gives us tools the tools we need to do as Paul says -
"Work out your own salvation in fear and trembling."
When I was Protestant, I puzzled over there not being a real answer to the question, “How do you grow in Holiness?” There was only more church meetings, not just Sunday but also Sunday and Wednesday nights, if offered, and of course the call to serve the local church was relentless [and a little overwhelming for me at the time, serving as a teacher with a full load in a public school, and coming home to handle all the cooking, shopping, cleaning, dishes, laundry by myself]. And also, most important, there was daily Bible reading and Bible meetings and Bible conferences, and lots of shiny new books on every subject of how to live scripture-based in every circumstance, and conferences led by the authors. It still left me wondering. Bible Study was wonderful, but it did not seen
enough to create a completely changed life and heart.
But Jesus founded a Church, not a book, and through the Church He gave us the Sacraments (as well as the Book!). And the Sacraments are
God’s Ordinary way of pouring down Extraordinary Graces. And its
Graces from Heaven that we need to grow in holiness. The
great fount of these is found
only in the Catholic Church.
Not to mention, we also need extraordinary graces to to actually be able to
be perfect, as our Father in Heaven is. God actually asks us in Scripture to be PERFECT! How can God ask us this?! Only because He provides for the miraculous graces for us to get there.
God gives great graces other ways; He is not limited. But to give them through the Sacraments of the Church that He founded, and promised the Holy Spirit to be with until the end of time, is the
ordinary way.
The proof that this is the absolutely ordinary way God pours out graces is in the very lives of the Saints, which are so available for anyone to read about. So many Saints, who became holy and perfect, in so many different and unique ways. There is nothing near like it to compare on earth for all time!
The Saints are the great witness of the Church. There is plenty bad to be found, but to judge the Church by that is dishonest. We don’t judge Jesus by the actions and ways of His beloved apostle, Judas Iscariot. So also is the Church not be judged by its weeds and tares. The right and just way to judge the Church is by looking at the people who actually live in obedience to Her teachings.
