The Bible definitely does refer to holy ones, or saints, that are in heaven. Jehovah is spoken of as “the Holy One [Greek, ha´gi•on].” (1 Pet. 1:15, 16; see Leviticus 11:45.) Jesus Christ is described as “the Holy One [ha´gi•os] of God” when on earth and as “holy [ha´gi•os]” in heaven. (Mark 1:24; Rev. 3:7, JB) The angels too are “holy.” (Acts 10:22, JB) The same basic term in the original Greek is applied to a considerable number of persons on earth. It certainly was true that all who made up the first-century Christian congregation were saints. (1 Cor. 14:33, 34; 2 Cor. 1:1; 13:13, RS, KJ) They are described as ones that received “forgiveness of sins” and were “sanctified” by God. (Acts 26:18; 1 Cor. 1:2, RS, KJ) Still, they did not claim to be free from all sin. They were born as descendants of the sinner Adam. This inheritance often made it a struggle for them to do what was right, as the apostle Paul humbly acknowledged. (Rom. 7:21-25) And the apostle John pointedly said: “If we say we have no sin, we deceive ourselves, and the truth is not in us.” (1 John 1:8, RS) So, being a saint in the sense that the term is used regarding Christ’s true followers does not mean that in the flesh they are free from all sin. Canonization officially recognizes a deceased Roman Catholic as worthy of universal and obligatory veneration. Interestingly, the New Catholic Encyclopedia indirectly admits that intercession by “saints” does not have a Biblical foundation. Many persons have prayed before images of “saints.” However, the apostle John told fellow believers, “My little children, be on your guard against idols.”—1 John 5:21, NAB. The Bible clearly shows that a Christian’s prayers should be directed to God in order to be acceptable to him. Jesus Christ pointedly said: “I am the Way, the Truth and the Life. No one can come to the Father except through me. If you ask for anything in my name, I will do it.” (John 14:6, 14, The Jerusalem Bible) We should not venerate or pray to any “holy one’ or Saint, All of our prayers should be directed to God through Christ Jesus.

well according to the catholic church, they are referred to mostly like deities, with them praying to dead people.
