2nd Timothy 2:15
rightly deciding the word of truth

*deviding*

And if you read first corrinthians then you can see Paul talking about circumsisiom and how it's no longer necessary. The bible makes a distinction between "the law of bondage" and the law of Christ

So christianity is like "we take the Jewish rules we like, but the rest are not relevane anymore"?

This is what Jesus says above all else, Love your neighbor as yourself, and love God with all your heart, mind, soul and strength. By doing these two things, you cover all the commandments.

Many laws that the orthodox Jew follows, Christians will regard as man made and not from God. God gave us the ten commandments, Jesus gave us 2. I don't know where the rest comes into play.

Contraceptives are banned for those of the Catholic Church. At last the clutch of hysterical head virgins deems it proper for million to die for the sake of not sinning. A third divorce is also frowned upon in the Orthodox Church generally.

Complete free thought seems to be highly frowned upon too in many denominations....

check the ten commandments,swearing,homosexuality,working on the sabbath(sunday),lying,cheating,boasting,killing,using the lords name in vain,and some other things.

God gave us the ten commandments, Jesus gave us 2. I don't know where the rest comes into play.

Almost all of Leviticus is additional rules, such as for what to eat (or not to eat), how to make offerings and atone for sins, how to remove diseases (which was more than bathing and quarantine: at multiple points [Lev 15:14-15,29-30] it says you should have a priest sacrifice two birds), legal codes (Lev 19), and a lot more. Some denominations say that they are still in effect today, while others say that those laws were made specifically for the Jews brought out of bondage. Some of these don't make sense today ("Do not wear clothing woven of two kinds of material" Lev 19:19, "Do not hold back the wages of a hired worker overnight" Lev 19:13, Don't eat fruit from a new tree until 3 years have passed Lev 19:23,24, "Do not cut the hair at the sides of your head or clip off the edges of your beard" Lev 19:27), but there are relevant ones (Do not lie, do not steal, do not pervert justice, do not defraud or rob your neighbor, keep your measures accurate).

think of something you like and bam, it's banned.
