I have a hard time understanding exactly the question people are asking or their comments if replying. So my answers might not really be the best - I think what you are asking is something like "What makes Christianity different from all other religions?" 'What makes it unique?"
I can answer that question and hope that is what you are asking. If not - well , the fault in understanding is mine so please do not take offense.
1) The main thing Jesus taught in the Gospels is that He is God the Son. That is the primary thing we are to get from the Gospels, it seems to me.
2) Christianity is an historical faith. The Gospels claim to be historical accounts - the resurrection of Christ in bodily form - He is said to have risen from the grave - if this is true it shows that he pleased God and that His claims are true.
3) Paul wrote about this in 1 Corinthians chapter 15 3-8. There is a consensus amongst scholars - believing scholars and those who do not believe - that these verses contain and a creed that goes back to within months or the resurrection - Paul must have gotten this from the other apostles in year 36 - maybe 3 years after the resurrection but the teaching goes all the way back to day one. At the time this was a public event in the Christ appeared to many people in various times. So we are asked to evaluate this as an historical event - to make up our minds on that basis - are these people credible witnesses or not.
How many other faiths make these claims?
3 For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, 4 that he was buried, that he was raised on the third day in accordance with the Scriptures, 5 and that he appeared to Cephas, then to the twelve. 6 Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. 7 Then he appeared to James, then to all the apostles. 8 Last of all, as to one untimely born, he appeared also to me 1 Corinthians 15:3-8
