Who and How of Salvation

Let's look at this one from yet another angle in hopes of gaining clarity.

In old Hebrew tradition, what Christians call "salvation" was had by all people who:
A) Repent (fancy word for "turn away from sin" or, literally, "change your mind" about sin)
B) Put their faith in God
C) Demonstrate their faith by obeying God's commands (7 for Gentiles, 613 for Jews)

But how is this accomplished?


CHRISTIANITY
Christians (generally) believe Jesus is the Son of God and that He came to Earth as a sacrifice to pay the penalty for sin. During His ministry, Jesus kept pointing to the above methodology for salvation of those following Him. From the official beginning of His ministry, Jesus preached repentance, continually urged faith in God, and constantly commanded good works. This is not salvation by works, but rather, it is a salvation by faith and the demonstration of faith is the good works. And the faith happens by way of repentance (changing one's mind and turning away from sin). Salvation is a free gift of God to any who repent and put their faith in Him. 

For the record (and this is not an all-inclusive list) and generally speaking, Christians who do the above and attend denominations are included among those who will be saved. Among them: Catholics, Lutherans, Baptists, Methodists, Mormons, Seventh Day Adventists, Presbyterians, Episcopalians, and more.


JEWS
The Torah is the origin of the three facets of salvation listed above. Deuteronomy 20, among many other passages, outlines God's plan perfectly, and coincides with the above summary. The Law was given that Jews may have a set of rules, the adherence to which helps set them apart as a nation. Jews are not expected to keep every Law, and not every Law applies to every Jew, but each Jew is expected to do his best. That is the essence of repentance in Jewish tradition. The adherence to the Law is part of demonstrating their faith.

Again, it is not salvation by works, but it is works as a show of faith.


NOAHIDE
The Noahide code, or seven rules for gentiles to live by, contains within it salvation for non-Jews. Again, this is not salvation by some set of laws, but is salvation by the grace of God, through faith. the faith comes via repentance, and is demonstrated by works - same as with Jews and Christians. The Gentile has seven guiding principles when it comes to the good works he/she is to perform to demonstrate his/her faith.
