There is no such thing as a saint with a capital S and one with a lowercase s with God.
His people are His saints and those who are born again know who they belong to and are called saints.
Your version of sainthood with a capital S is only another of fallen man’s attempts to elevate himself above others. And, again, I say that when you are filled with the Holy Spirit this truth will be made known to you.
Capital "S" saints are simply saints that are formally recognized by the Church.
If you're concerned about un-biblical practices, you should know that Luther's dogma of "the Bible alone," as the sole rule of faith, isn't in the Bible.
Making *Saints* of people is being respecters of persons, a sin according to James, the author of the Catholic’s favorite book of the Bible.
