"Holy man / saints" in the point of view of God according to the Calvinist? I was in the middle of a discussion in a Christian Forum, where the Calvinist member say that : "holy man / saint" can only exist only after Jesus died. Before Jesus died, all the OT people are neither holy nor saints, they are sinners - even soon after they died they are not holy/saints because they haven't been freed from their sins and their original sin by Christ's blood.


  2 Chronicles 23:6 But let none come into the house of the LORD,
  save the priests, and they that minister of the Levites; they shall go
  in, for they are holy: but all the people shall keep the watch of the
  LORD.
  
  Psalm 34:9 O fear the LORD, ye his saints: for there is no want to
  them that fear him.
  
  Deuteronomy 33:3 Yea, he loved the people; all his saints are in
  thy hand: and they sat down at thy feet; every one shall receive of
  thy words.
  
  Ezra 8:28 And I said unto them, Ye are holy unto the LORD; the
  vessels are holy also; and the silver and the gold are a freewill
  offering unto the LORD God of your fathers.


It's the same question which I ask to the Calvinist member in that forum, but I don't get a satisfying answer from them as their reply starts to going around and around, jumping here and there.

So... my question is:
From the verse above - how come they are being said as "holy" or "saints" if according to the Calvinist, OT people are not holy/saint yet because the blood of Christ hasn't cleanse them yet ?
Unfortunately, the Calvinists in the web forum mentioned are misrepresenting the Calvinist position on Old Testament saints.

Westminster Confession of Faith 11:6 states: "The justification of believers under the Old Testament was, in all these respects, one and the same with the justification of believers under the New Testament." (Westminster Confession of Faith Chapter XI: Of Justification.)

In context, it refers to the fact that justification is according to God's decrees for all the elect on the basis of Christ's death, with numerous additional clarifications. The point is that Christ's blood was equally efficacious for them.

Occasionally, you will hear Calvinist objections to calling a person, "Saint Such and Such," not because they believe it is incorrect, but because they think it can imply that there are special categories of Christians who qualify to be saints, while others are not. This has more to do with objecting to the Roman Catholic view of granting certain Christians sainthood after they die. 

To Calvinists, a person who is in Christ by faith is a saint, and prior to the incarnation, there were Old Testament people who were in Christ.
