Why does Judaism call their good people RIGHTEOUS and some Christians make saints in special ceromonies?

In the bible, the Greek word rendered Saints is also rendered as holy ones so let me show you the difference between what different ones teach and the bible so you can see.

Religious teaching:

According to Roman Catholic teaching, saints are those who died and are now with Christ in heaven and who have been given recognition by the Church for outstanding holiness and virtue. The Tridentine profession of faith states that the saints are to be invoked as intercessors with God and that both the relics of saints and images of the saints are to be venerated. Other religions, too, invoke the help of saints. Certain religions teach that all of their members are saints and are free from sin.

The bible:

The Bible definitely does refer to holy ones, or saints, that are in heaven. Prior to John the Baptist no one will go to heaven but are given a resurrection to the earth (Mt 11:11,12; Mt 5:5; Ps 37:11,29) hence the reason why they are called Good and not Saints or holy ones. God 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.

For example:

Acts 9:32, 36-41, JB: “Peter visited one place after another and eventually came to the saints [ha·gi′ous] living down in Lydda. At Jaffa there was a woman disciple called Tabitha [who died] . . . [Peter] turned to the dead woman and said, ‘Tabitha, stand up’. She opened her eyes, looked at Peter and sat up. Peter helped her to her feet, then he called in the saints and widows and showed them she was alive.” (Clearly, these saints were not yet in heaven, nor was just an outstanding individual such as Peter viewed as a saint.)

2 Cor. 1:1; 13:12, JB: “From Paul, appointed by God to be an apostle of Christ Jesus, and from Timothy, one of the brothers, to the church of God at Corinth and to all the saints [ha·gi′ois] in the whole of Achaia.” “Greet one another with the holy kiss. All the saints send you greetings.” (All these early Christians who were cleansed by the blood of Christ and set apart for God’s service as prospective joint heirs with Christ were referred to as saints, or holy ones. Recognition of their being saints was obviously not deferred until after they had died.)

Consequently, they do not become “holy ones,” or “saints,” by decree of a man or an organisation, but by God, who brings them into covenant relationship with himself through the blood of Jesus Christ. The term “holy ones” applies to all those thus brought into union and joint heirship with Christ, not to a mere few considered to have exceptional holiness. It is also applied in the Bible to them from the beginning of their sanctified course on earth, not being deferred until after their death. Peter says they must be holy because God is holy. (1Pe 1:15, 16; Le 11:44) All the spiritual brothers of Christ in the congregations are frequently called “holy ones.”—Ac 9:13; 26:10; Ro 1:7; 12:13; 2Co 1:1; 13:13.

So as you can see, what the bible terms holy ones include basically all in heaven including God and his son Jesus Christ, angels and those who have gone to heaven along with those destined for heavenly life.

Some teachings of Saints is a religious not a biblical teaching and therefore you will find a greater variety in these from religion to religion. Some who have even been venerated by men as Saints through churches have killed or lived questionable lives according to bible standards. That is why it is God who does the choosing of who is and who is not saints according to scripture.

No, no, no, Jeffrey! Then certainly everybody might confuse them with the "Christians" who wood funerals with anti-gay slogans and the "Christians" who get on television and bilk little previous females out of their social safety tests to purchase themselves extra beneficial limousines ... they have already got the cognomen of 'Christians against Jesus.' We would not choose to reason confusion, now might we?
