Where in scripture does it say believers are saints?

Answer 1

There are many scriptural passages that could be referenced to answer this question, but for example, see Eph 1:1, which support the notion that saints are still living (as opposed to the Roman Catholic doctrine that supports the notion that saints must be deceased).

Eph 1:1 (ESV)Paul, an apostle of Christ Jesus by the will of God, To the saints who are in Ephesus, and are faithful in Christ Jesus:

True Catholic View:

Catholics firmly believe in the Doctrine of the Communion of Saints and, in fact, it was developed by Catholics. All living persons in a state of grace in the eyes of God are saints. All souls in Purgatory are saints. All those in Heaven, known and unknown, are saints. The canonization process is simply an investigative process carried out by the Church to verify that a candidate for sainthood is indeed in Heaven and worthy of veneration and emulation. Only God can make a saint and only God is worshiped. If you answer a question in Saints, which is a sub category of Catholicism, it is best that you leave the question to a Catholic to answer.

Answer 2

In the New Testament, the term "saints" is often used to refer to believers in Christ. For example, in the letters of Paul, he frequently addresses his audience as "saints" (e.g., Romans 1:7, Ephesians 1:1). This signifies their status as set apart for God and part of the community of faith.
