You aren't the only person who's ever wondered what Christianity is. Christianity is an Abrahamic monotheistic religion, based upon the life of Jesus of Nazareth. It is the largest religion practiced worldwide with approximately 2.6 billion members. That's about one-third of the world's population.
In a series of petitions, Christian leaders asked Emperors to grant the same exemption from state and cults that they granted the Jews.
The Christian tradition has shared many of the same beliefs over the years as the Jews. The New Testament clearly shows that there is an inextricable link between the two. The Christian Church, an important part of Rome's empire during the Middle Ages was represented by Christian leaders who repeatedly asked the emperors for the same exemptions from state cults that they granted to the Jews.
The Christian Bible is composed of two major parts: the Old Testament as well as the New Testament. The Hebrew Scriptures of the Old Testament are included in this section. Christians believe they were inspired by God. The New Testament comprises writings by Christian believers who claim Jesus is their follower.

Christians believe in the Holy Trinity
Christians believe God is a Triune God that includes the Father, the Son and the Holy Ghost. Each of them have different attributes and roles that make them distinct from each other. The Father begotten the Son as the first Person of Trinity. The Holy Spirit proceeds from God and continues to the Son. The Persons of the Trinity also have their own "missions". The Second Person of Trinity, for example, becomes incarnate and suffers death before ascending to the Father.
The Trinity is a fundamental concept of Christianity. The Christian belief holds that God is one and has three separate persons. These three distinct persons are Jesus Christ, God the Father, and the Holy Spirit. Each of these three Persons are equally powerful and important.
The important doctrines of Christianity include Jesus' ascension, resurrection, death and resurrection.
The most important doctrines of Christian faith are Jesus' death, resurrection, and ascension. They give Christians hope after death that they will be raised again and one day will be with God. Accordingly, the New Testament is centered around Jesus' ascension.
The resurrection is the foundation of Christianity. Without it, Christianity would not be a religion. Christians wouldn't have any hope of justification and forgiveness without the resurrection. Jesus was able to prove his unique status of Son of God through the resurrection.

It is based upon a specific experience or scheme that is directed at saving.
Christians believe in redemption and a plan for salvation. They consider themselves in need of a Savior. Christian doctrines are based on the idea Christ died for all of humanity's sins, and bringing us back in relationship with God. Christians believe Christ's sacrifice is the foundation of our salvation.
