Questions for Jews

Questions for Jews Hi! I am a Catholic and I really have a lot of questions.

Is there any Jews or even other who wants to share from external views that can help me?

First, my logic is that, if I am trying to believe in catholic concept, then I should know who HE is right and i think the infos can be better obtained to the Jews since that is where it started from.

So i have a question first about the prophesy of the messiah

-is there something that says about he will save us or he will pay for our sins?

Second, are jews the only one that is loved by HIM? Like i learned about gentiles which is us (non jews) so am i not welcome?

Third, is there a concept of salvation? Is that in the prophesy?

Thank you and i am hoping to discuss more.
