Aulef:
As far as I know, it is a protestant principle to not have saints.
Well, depends on what Protestants you are talking about.
Yet, even those Protestants from “low church” backgrounds still believe that there are saints. We just apply the term to any Christian living or dead. A saint is literally a holy, sanctified person, and all truly born again people are by definition holy and set apart to God.
So, we use the term saint in the way that Paul uses it in his epistles. For example, Paul greets the Christians of Ephesus in the following way in Ephesians 1:1, " Paul, an apostle of Christ Jesus by the will of God, To the saints who are in Ephesus, and are faithful in Christ Jesus." Literally, he’s addressing his letter to the “holy people who are in Ephesus.”
We also have heroes of the faith who we commemorate and remember for their lives and acts of faithfulness, but we have no need of any official process for recognizing them. Their lives and actions will speak for themselves.
