There is the common usage most Catholics use to refer to those who are examples of holiness, and there is the official definition of the Catholic Church.
The Catechism of the Catholic Church #946
After confessing “the holy catholic Church,” the Apostles’ Creed adds “the communion of saints.” In a certain sense this article is a further explanation of the preceding: “What is the Church if not the assembly of all the saints?” The communion of saints is the Church.
So, if a person is a follower of Christ, they would be a saint. However, in the Catholic Church, Saint has become a word used to refer to those saints that are examples of holiness. Therefore, most catholics when asked would say “I am not a Saint!”
There is a “language barrier” here. I hope you can acknowledge and understand the development of the word saint into Saint. We are all saints, but not Saints.
