Use 1 instead of 0.999999999... to Fight Satan
The significant difference between Judaism and Christianity of course lies in the concept about the God, but also in the concept of Satan, devils, and evil spirits.
It should be understood that Christ Jesus, who was at least God's Son, was attacked and finally killed by Satan and its minions, since Satan is an enemy of the God. To kill Christ Jesus and crush the good wishes and good intents of the God to save people, Satan used Roman soldiers, priests of Judaism, and Judas. The story of the Bible (New Testament) tells what Satan is: a complete enemy of the God and, therefore, men. But, Judaism does not take the same view, although it has its version of the concept about Satan.
According to the Gospels, Satan is an enemy of the God, Christ Jesus, and His followers. Satan represents evil spirits trying to destroy men's faith in the God and Christ Jesus. Satan is the main source of evil and every bad thing for human beings. Satan is an enemy of Christianity and followers of Christ Jesus, but for Jewish people, the sin of Christ Jesus calling Himself a Son of the God might be more significant and graver than the sin of Satan obstructing some intentions of the God.
Judaism does not put a great weight on the concept of Heaven, the hell, Satan, and the fight between good and bad. Judaism thinks much of worldly peace, prosperity, morality, virtue, etc. in addition to the pride that Jewish people were uniquely and especially chosen by the God.
Christianity regards the fight against evil spirits and Satan, in addition to having faith in the God and Christ Jesus, as the highest mission as well as the sacred duty.
You may judge some Jewish men to be the best from their words, attitudes and ways of living. But there is no way to judge any Christians to be the best from their words, attitudes, and ways of living; only the God and Christ Jesus who can see their insides and content of their belief can judge them. In this context, being a priest or even the Pope cannot assure that he is the best Christian. Satan can enter a mind of any body some time.
Moses did not say that the God had said to him not to follow Satan, which was therefore not written on the slate with the Ten Commandments. Christ Jesus also did not say to watch out for Satan when He was temporarily dying on the cross.
But Satan appeared in person before Christ Jesus in the wilderness to destroy Him, which it failed. How could Christ Jesus forget about or forgive Satan? The hidden theme of the Gospel should be the fight between Christ Jesus and Satan.
On the other hand, the story of Judaism is also based on the fight between the God and Satan, which however seems not to be realized by Jewish people. The God purged Adam and Eve from the paradise, which tells that Adam and Eve sold their souls to Satan. The God once tried to destroy all the people except Noah, which tells everybody except Noah sold its soul to Satan. The God sometimes forsook Jewish people so that they became slaves in Egypt and prisoners of war in Babylon and they were defeated and ruled by Alexander the Great and the Roman Empire, which tells that the God must have found many among Jewish people who sold their souls to Satan. It looks like when Jewish people sold their souls to Satan, the God neglected Jewish people but when they repented, the God saved them.
Satan has not targeted only Jewish people but all the mankind. Therefore, Christ Jesus sent his disciples to the world to fight Satan and save all the races, tribes, and people from Satan. However, Judaism has no strong sense of mission to fight against Satan. If Satan says that it believes in Judaism, Jewish people might accept it. But even Satan says that it believes in Christianity, no Christians would accept it, since Satan is an incontestable enemy of Christ Jesus.
In this context, Jewish people might believe that even if they accepted Satan, the God would finally forgive them. But Christians must know that if they accept Satan, Christ Jesus would not accept them.
However, it is difficult to reject Satan, as none dislikes money, a tool of Satan. Even Christian priests and the Pope like money like Judas who sold his soul to Satan for money. But Jewish people seem not to find the sense of sin in loving money, since they are not followers of Christ Jesus and Moses did not say not to love money.
If the God is the infinite, Satan is metaphorically 0.999999999... (= 1/3 x 3 = 1) which is mathematically 1. Satan imitates the God by taking a figure of 0.99999999... in the form of a decimal number that accesses one forever as if taking access to the infinite.
Judaism looks like a religion to accept 0.999999999... instead of 1. Christianity looks like a religion not to accept 0.999999999... but to use 1 instead not to accept Satan.
**** **** ****Matthew 12 King James Version
5 Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless?
6 But I say unto you, That in this place is one greater than the temple.
7 But if ye had known what this meaneth, I will have mercy, and not sacrifice, ye would not have condemned the guiltless.
8 For the Son of man is Lord even of the sabbath day.
