We are saints either way, because when Jesus died on the cross, we were Justified (declared not guilty) for ALL of our sin, past present and future.
Our Sainthood has nothing to do with our actions.
Actions speak louder than words. A person proves he is a saint by the actions of good deeds. "Not everyone who calls Me 'Lord' shall enter the kingdom of heaven." "Why do you call Me 'Lord, Lord' and do not do what I say?" "He who hates his brother is in darkness until now." "Faith without works is dead."
The reformed response to the cry of "antinomianism" is: we are justified by faith alone, but not by a faith that is alone." IOW, justification is by faith apart from works, but that faith in Christ in which righteousness is imputed is also a faith that produces the works of Christ. Anyone who claims they believe in Christ, but don't follow what He said, is not someone who is justified. Those who are justified by faith are those whose faith motivates them to follow Jesus and obey what He said. This is what James 2 is all about.
Therefore, when you claim "sainthood has nothing to do with our actions," It just seems to me you don't know what you're talking about. James is clear about actions showing who we belong to, as well as 1 John, as well as 1&2 Peter, Jude, and scattered throughout the epistles of Paul. "If you live according to the flesh, you shall die; but if by the Spirit you put to death the deeds of the flesh, you will live." "Be not deceived, God is not mocked; whatsoever a man sows, that shall he also reap; if you sow to the flesh, you shall from the flesh reap corruption; but if you sow to the Spirit, you shall from the Spirit
reap everlasting life."
So then, anyone who has faith in Christ without works does not know he is saved until he is doing the works that Jesus and His apostles commanded to do. Doing the good works not only is proof of who we belong to, but it also brings healing to the soul and (by the Spirit) sanctifying character to a person's life. Indeed, the good works done must be done by faith in God, not under the assumption that one is doing those works on their own. This is the point of faith and working out one's salvation with fear and trembling - that God is at work in us to will and do His good pleasure. (Phil. 2:12-13)
Therefore, faith in Christ is not without a full attachment of works that follows, and it is by those works that we are known to be saints. But this response of yours begs a question: are you a universalist? Do you think that everyone is justified by Jesus dying on the cross? Or do you believe that only those who have faith in Christ are justified? And then, what kind of faith are you talking about?
