Catholics believe exactly what is written in the Apostles' and the Nicene Creed:
Nicene Creed (4th century) :
We believe in one God the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds, God of God, Light of Light, Very God of Very God, begotten, not made, being of one substance with the Father by whom all things were made; who for us men, and for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the Virgin Mary, and was made man, and was crucified also for us under Pontius Pilate. He suffered and was buried, and the third day he rose again according to the Scriptures, and ascended into heaven, and sitteth on the right hand of the Father. And he shall come again with glory to judge both the living and the dead, whose kingdom shall have no end.
And we believe in the Holy Spirit, the Lord and Giver of Life, who proceedeth from the Father and the Son, who with the Father and the Son together is worshipped and glorified, who spoke by the prophets. And we believe one holy catholic and apostolic Church. We acknowledge one baptism for the remission of sins. And we await the resurrection of the dead, and the life of the world to come. Amen.
Of course Catholics believe that the Catholic Church is the Church founded by Jesus Christ himself.
As for Judaism, there is no single binding view of Jesus. One thing all Jews agree upon, however, is that Jesus is not in any way God.
There are many views of Jesus that circulate in Judaism, ranging from sorcerrer, apostate, heretical rabbi, son of a Roman soldier (most of these are found in the Talmud) to simply a misunderstood Rabbi who was crucified by the Roman state and subsequently proclaimed (falesly) by his followers to have been divine.
